Nile talks about lab safety: • Chemistry is dangerous. - Věda a technologie
Waste disposal and management is an often forgotten and obscured part. People love to see reactions and might think to do these things themselves, without thinking about the disposal process. This video is invaluable, since it shows it's not all fun and games.
I agree!
Yes, good reason not to experiment with mercury, lead, etc.
Waste disposal is easy.
1) Political donation
2) Dump it anywhere
That's why i really rather watch it than to do the experiment
What scares me is imagine all the people who DONT see this and just flush waste down the drain. Its a shame people can be so ignorant.
Am I the only one who barely understands these videos but find them very interesting?
I understand a lot of the basic chemistry, and the rudimentary molecular physics behind it, but my memory is so far gone that I can't retain the formulas or even the chemicals for more than a minute or two. The ideas, yes, but not any specifics. The organic chemistry just completely loses me after two or three reactions. Still immensely interesting though.
Chamous x Yes
They are interesting. You don't have to dumb things way down in order to make it interesting for a layperson. You can still get the gist of it.
Chamous x I'm not an english speaker
I'm very good at chemistry in my language but in english I barely understand (I'm Romanian Na2S in romanian is Sulfat de Sodiu not Sodium Sulfite)
You'll learn something,so thats quite good

I usually just add a wad of bare copper wire to my waste mercury jug and get pure mercury metal in one step, But I have always wanted to see this method. Any chance you can convert it to the red mercury sulfide? I haven't figured out how to do it yet.
I always wondered how you clean up your waste cody :D
It's funny that I honestly never thought of just adding a metal to reduce it. That is probably the better way, ha. I imagine is takes a long time though.
I think to convert it you need high temp and pressure or something. In the end, the chemistry of the two kinds are pretty similar. Why do you want the red sulfide? As a dye or colorant?
I'll be trying to do this pretty soon, actually. I'm after a full set of historical paint pigments and so I'm intentionally making mercuric sulfide for it. There are vague references to the black sulfide being heated to temperatures in excess of 300 degrees celsius to convert its crystal structure to that of vermillion, and even to sublimation occurring at those temperatures. This could be useful for separating the mercuric sulfide from your celite, NileRed. I'll let you all know of my findings when I get around to it.
I think it would be pretty interesting to see a liquid metal being cemented out onto a piece of solid metal. Especially copper with its deep, cold-coloured ions.
Would the Hg bead up and only fall when it gets big enough? Or would it appear absolutely everywhere in the form of microscopic drops like condensation?
Amos Z Historical paints? I just did a video on Prussian Blue, and I really wanna make Mauverine, but that is just too expensive!
This is amazing - finally a channel that has modern, accessible, sciency high-quality videos on waste treatment. Great idea for a series, my chem department is going to love this!
Glad you liked it!
NileRed please do a video on C10H5ClN2...pleeeease.
"my chem department is going to love this!"
no, they aren't. the things Nile does are slipshod and VERY sloppy.
no chem professor in their right mind would use these videos of anything except as examples of how NOT to do these things.
"Good enough" is not what a good professor teaches.
@@thomasneal9291 like... could you elaborate? Rather than just claim that hes sloppy and a bad chemist.
Personally, he reminds me of my microbio teacher, and my ap chem teacher, making lab work fun and interesting and easy to get a better understanding than a textbook
I think if I ever had to do this much work to clean up back in grad school I would have just quit. Kudos to you for doing the responsible thing and cleaning this up properly. Such a mess....
haha yeah. I miss the luxury of just putting it in a container and forgetting about it.
17:47 a very very fatal lemonade

well he poured it down the drain so it probably isn't that lethal
@@thefableparable215 You're not swallowing what your pouring in the drain... It had bleach...
Just noticed you have "NileRed" printed on some of your beakers.
Pretty legit.
Waste recycling videos are really useful for lab techs such as myself. I know my college lab would love to see them continue!
Sounds good!
I'm not a lab tech or anything but more extraction videos is more better for me too!!! i would love to see them continue myself x3\
{{REASON REDACTED}}
Pollution control is very important!
Your college doesn't have a protocol for disposing of waste?? That's bad. Real bad.
College labs (or ANY commercial lab) will require waste to be sent out. Trying to treat your own waste is irresponsible. As we all know reactions and experiments don't always go properly or to completion.
The way the filter paper floated to the bottom of your makeshift filter was rather gratifying.

First chemistry lab at university was like this per experiment: 5-10min getting the stuff you need, 10-15min the actual experiment, 30min-2h waste management.
NileRed: Complicated filtration cycles.
Me: FUNNY COLOURS!!! YAAAY!!! Do more funny colours! :D
Very practical use of chemistry and educational from several standpoints. Thanks for your posting. After thought: If you sandwich the diatomaceous earth between two sheets of "fast" filter paper it is easier to deal with.
that is a very good point. I didnt even think of that
lmfao I wrote the exact same comment
9:19
Ok did anyone else find that the filter paper just falling so perfectly to be satisfying?? Or just me...?
I came to look to see if anyone said anything about it. I also thought it was strange
i suggested videos like this a little while ago, so happy you are doing it. it show's an interesting side to chemistry that doesn't get covered much
Great video, as always. I have suggestion for future synthesis - the Crystal violet dye, also known as gentian violet. It can be used for staining biological samples (like Eosin), it has some antibacterial effects and it can be used as pH indicator. In strongly acidic solutions, the color of the dye changes from violet to green and to yellow. In basic solutions, it decomposes and becomes colorless.
Dirty Mercury??
Dang. Well, now that I got the name, I better go recruit some bandmates!
What kind of band? Heavy metal?
@@BugsydorPrime Of course, but especially death metal.
I really enjoyed this video. It gives another angle to chemistry that not many CZcams's take advantage of. Great work!
Its really nice of you, that you handle contaminated stuff with such care, instead of just washing them down the sink. I am interested in more contamination related videos in the future :)
When filtering with DE (Diatomaceous Earth) you can continue to add small amounts of DE while you are filtering to keep the filter surface from being blinded. This keeps the filter process from slowing down.
Excellent video. Kudos for demonstrating responsibility.
Excellent series. Waste disposal was a big concern for me in the past. Not doing any chemistry now. Found your channel to be very enjoyable to watch.
Love this series already. Waste processing has always been something that interested me
Assuming this is a process used on a scale this size it makes one question what to do with an entire great lake. At least in western Lake Ontario they're dredging the PAH. The volume is astounding. Your informative video shows it's perhaps best to deal with such issues while they're still within more manageable volumes. Thanks, as always, for providing such informative videos.
It appears that you did a good, thorough job, and I am glad to see that you have the responsibility to (attempt to) properly recycle the chemical waste. Thank you.
tbh I find the waste disposal process the most interesting stuff. I've always wondered about what happens to chemical waste and always got oblique answers when I asked. Showing the waste processing feels behind-the-scenes
I will admit. I don't know much about chemistry. But I can't seem to stop watching these videos. Very educating and interesting. Learning alot. And loving it. Keep them coming please.
I love your videos so much, because I rarely can make experiments so I can watch them only lol. Also, your voice is cool!
haha, thanks!
Yes, the same goes for me. And did you notice that this really is the first Comment on that Video, the one you've posted?
Florian Daßler Yes 😂 This is the first time that I'm early.

I think this is a wonderful idea - I mean making a series of waste recycling. It is very important to see what happens after your reactions. And you made it very interesting as well! You should do this more often!
I like to listen to this at 2 am and it really helps me sleep, your voice is very calming.
after seeing this I'm very curious how they deal with this stuff after you've given it to the disposal people
They neutralize and react the waste into unharmful chemicels. Then dump it
dump it where
@@margiethenunblessyoursoul9946 somewhere
@@matan7899 Okay um what's an "unharmful" mercury-containing chemical then?

Great to see such a responsible video. The only thing I would make sure in the future is, never use water bottles for any chemical storage - but if you do make sure is it clearly labelled with hi-viz labels so if someone else is coming along behind you they know exactly whats in the bottles. keep up the great videos.
NileRed, I love your videos. They are so well put together and nice to watch. In fact, I'm watching this a second time!
Thanks! I am glad you liked it :)
I appreciate your care in disposing your chemicals. Respect.
Couldn't you add another filter paper on top of the sand, to prevent any of the sand from getting displaced?
Alot of mercury sulfide would still go through it and into the sand tho. But it could increase the yield of non-mixed sulfide.
Yeah that's what I was thinking. We essentially did that with our protein purification chromatography columns to stop the separation media getting churned up. Works well, would recommend :)
me and 5 other people said this and he said he didn't even think of it

Neat video. I'd like to see lead waste recycling, mainly Lead (II,IV) Oxide (red lead). Should be able to react it back into metallic lead with a hot enough furnace and a reducing agent.
Very useful and informative! I hope you will keep going
Great idea for a series. Really informative and interesting!
awesome video man always super informative. your actually inspiring me to take chemistry any tips on pursuing chemistry as a career ?
Make sure to take sciences in high school and then choose to do chemistry in university. While you are doing your undergrad, youill have to decide whether you want to work in academics or industry.
+NileRed yeh I'm actually talking to an administrator at a college close to where I live so I'm gonna take an intro test next week
Good luck man! Keep the STEM alive!!
So are you in chemistry now? Hows it going?
op please update i need to know how your science journey is going
"It gets too basic" soon Starbucks will be everywhere
So thorough. N yr explaining, is so good. Tyvm
Excellent idea to make a video on chemical waste management. Truly amazing. Looking forward to many such videos.

Very interesting. :) Could you do a video on dealing with halogeneted wastes? Those containing Chlorine and Bromine and stuff like that? (:
brilliant, love all your videos. you have helped me so much in my adventures though consciousness
so many people doing chemistry on youtube clearly have no idea what to do with waste so it's great to see this. these might be your most important videos
I really like these videos on safe disposal. I think for anyone who likes to experiment it can be really useful to atleast know how to deal with waste. Personally I'd love to see something on the safe disposal of chromium salts/solutions(dichromates)!
I'm a simple human being.
I see "Mercury", I click
I'd long been curious about how you dealt with all of the chemical waste that your experiments generated.
I have a new respect for the people who process toxic waste -- although it almost seems as if you generate as much new waste (e.g., paper towels) as you recover.
Thank you for posting this video. If I ever use mercury salts, I'll be sure to study it.
The quantitative precipitation of mercury sulfide works at a pH = 0 - 1 as well. No need to put in large quantities of NaHCO3. During the ion separation procedure in analytics you will bubble in H2S-gas into the acidic solution with a pH of about 0-1. HgS 's solubility product is VERY low!😉
Waste disposal is just another part of the deal and by no means glorious but very important. I really enjoyed this video, just like the other ones you put up
Very echo friendly. Respect
Wow currently I’m taking an Analytical Chemistry course and I was learning about complexes and qualitative inorganic analysis and watching this video I can understand some of the things you are saying
I love waste management. It is an interesting part of lab work. You have to be creative and adaptive because every batch of waste is unique.
6:51 looks awesome :D
The whole process looks messy and tedious, but very interesting. One question remained though: How do the specialised facilities process the contaminated solid waste?
If it safe to burn just lit the things up. As far as I know all biocontaminated scalpels go back to liquid steel.
@@vjaceslavsavsjaniks6431 You can't burn an element though, no matter what compounds you make you'll always have Mercury atoms.
They ship to SEA country dump it here. That's how waste management in the west works
@@ThoolooExpress some mercury compounds are safe.
@@Kyle-gw6qp Yeah, I'm aware of that, I was just explaining why you can't burn it and expect whatever's left to be safe (and also not potentially create toxic fumes).
love your stuff Nile Just ordered some merch as a gift.
Thank you, that you show us how to deal with hazardous substances!
"Over the years I have collected a decent amount of waste" ... your entry for the worst pickup line in 2017? ^^
I usually just pour my mercury waste in a duck pond at the park. Funny though, all the ducks died recently for some reason.
hmmmm, that's so strange
maybe pouring in more will help?
Yeah I agree, they’re probably just hungry. Poor ducks not being fed enough mercury smh
This is the first video I've seen on waste recycling, it would be useful to see one on even more mundane things that have steps.
Very interesting and useful, love to see more like it... we should do what we can to protect the enviroment.
Hello. I would like to know if the plastic and other containers in contact with the waste Mercury remain contaminated. If so, how is it dealt with?
do a qualitative anorganic analysis series in which you showcase the tests for different ions
I think what ill end up doing is several small videos and then compile that into one mega one
you could also try to detect ions in waste, soil or sth like that to see/prove whats in there :)
This is the first time i find chemistry to be so interesting, i´m a civil engineer, took 2 chemistry classes, witch were mandatory some 15 years ago, i really suffer those, this on the contrary, i find really amazing and entertaining. Great job. ( i dont understand much, but i find your videos really appealing and well edited, and interesting)
That is a great idea for a series, actually! Lacking knowledge on how to deal with chemical waste is one of the main things that prevents me from performing more extensive experiments..
Also, I do assume lead is processed in a very similar way?
I really think you need to seriously consider doing an ICP analysis on your waste material to prove that it's safe to discharge as wastewater.
Yeah, definitely could use a double-check.
Just drink it, if your fine it's safe to pour down the drain.
You need to build yourself a proper fume hood because those bubbles bursting
are emitting mercury vapors.Include a carbon filter to catch noxious gases.

I like your Videos. They seem simple, to the point, and a step by step process of what you are doing. I wouldn't mind if your voice sounded a tad more interesting, however I am glad it also isn't over the top for something like this.
It is also nice that you point out what you are doing correctly, incorrectly, and even point out your half-assed attempts. That type of honesty is what is needed when dealing with !!SCIENCE!!
Thank you for the intriguing and informative videos.
why don't you put a second filter paper over the celite to avoid getting it in your finally product
The problem is I’ve learned more about chem from this channel than I ever did in my honors chem class 😭❤️
very impressed you didn't throw it down the drain well-done

So every time you had to clean something out with water, did you effectively create more mercury waste?
Everytime he cleaned something with mercury in it. Yes.

I would love if you continue this chemical waste recycling series. It's so interesting.
Nice series. Keep it up!
Could you tell me more about your glassware? What makes it cheaper than others? Some short research shows the 500ml beakers are roughly 11 usd. Yours are 6 in comparison, are there compromises in quality? Looking into getting some glassware but I wanna make sure about things.
Where are you searching that it is 11 USD? I just priced mine similar to the price that I could get it from china, or locally. There should be no real difference. Some glassware is "thick-walled" which comes at a premium price.
Just from Amazon, however I just did another search and found another on Amazon with a similar price point. So maybe the first one I found was thicker. It didn't mention anything about thickness though.
hey just be grateful that he doesnt overprize them just because theres 'nileRed' written on them :D
Oh I am, I was just curious of how the pricing was decided is all lol.

Thank you for your videos.
The recycling videos are great because it is modelling good behavior.
As far as ideas for videos, I know you've done a lot of scents, can you do Geosmin? en.wikipedia.org/wiki/Geosmin
Or maybe extract what makes wasabi (or horseradish) so spicy?
I still want to see aspirin from bark too.
what isn't good behaviour though is how he stores his waste
100% wholly unprofessional.
+Justin Koenig
So what is the problem?
+Mad araH
Except that synthesis of aspirin and heroin has pretty much nothing in common.
Justin Koenig You're right. They should be in approved waste containers, or at the very least say something other than just "Hg" Most people don't know what Hg means. Also, leading people to believe that they can treat their own waste is more irresponsible. Don't try treating your own waste people!
user255 - not labeling the waste containers properly
-using food containers as waste containers
-who knows where this is stored? i assume it doesn't fullfill any standards set by the industry, though, seeing what he did here
Mercury is ESPECIALLY difficult waste to work with. breaking several regulations doesn't help.
I suggest adding a second piece of filter paper above the celite to be an isolation layer for the product inside the buchner funnel. This should facilitate the removal of the product while keeping most of the celite out of it.
Very nice to see the process.
"If things get more basic..." weil, I guess it would start a blog in tumblr
Do your neighbors think you are cooking meth?
I think the white sediment after Ca(OCl)2 treatment is gypsum, or any form of calcium sulphate.
Cause it has low solubility in water, and also it's white.
Ca2+ is being added to the mixture, while SO4(2-) forms during the reaction; then they just meet and fall down.
Awesome job Nile, 1 part of a PhD in chem that I missed out on is proper waste disposal. We always just bagged it up and paid an external company to come collect it (and hopefully dispose of it properly...) please keep them coming! As a purely hypothetical question (as in do not turn this into a video) how'd you dispose of Tl waste?
As a video idea we generated a lot of Transition metal waste, mainly as mixed oxides and potentially nitrides (N 3-)of V Ti Co and M, how would you dispose of that lovely little mixture?
I should never be a chemist. I'm not nearly organized enough to keep everything labeled. Probably end up accidentally drinking a bottle of mercury.
Seems questionable using "celite" for filtration, when you have no way of separating the filter medium from the precipitate!
Love the videos! Where did you get the NileRed beaker? Thanks for all you do!
I ordered a billion from china, ha.
