- Experiment for vision only, it is used to understand how the salt dissolved in the water facilitates an optimal condition for the passage of current between the two electrodes. The working voltage is 220 volts AC.
Required: 500W 220V bulb. Two conductive iron or other metal nails, glass tray. Salt water and two electric wires. - Věda a technologie
The arcing against the water is very cool!!! I should have expected it, but still surprised me when it happened.
The bubbles coming off the electrodes in the water are O2 and H, you can capture this in a test tube then make it burn with a match and get a nice pop. Don't use a huge bottle though as it is very explosive. To capture the gas, but a test tube of water over each electrode, as the tube fills with gas it will empty the water. The tube that fills first is the hydrogen and the slower one is the oxygen.
isn't is Clorine that is being producded? Cl2?
@@tammizeevi3995 Well, hmm. I don't know I'm not a chemist. I just learned about it in grade school. I thought the salt just got denser as the water molecules broke apart. I would trust you more than me.
@@LenHarms Both Hydrogen gas and Chlorine gas, but chlorine are easily soluble in water and thats why water is turning yellow at the end of this video
@@LenHarms but no oxygen molecule, cuz its easier to oxidise chloride ion than hydroxide
HH0 can be use as car gasoline
Salt is not producing the energy but conducting it as a metal with charges Na+ Cl- .on the periodic table Na is located on the left side and Cl on the right due to the need of valence electrons, in this case Cl requires one and why has a charge of minus (-1) to complete the octon rule, so in other words Cl consists of 7 valence electrons. Salt is also considered a crystal salt due to the properties just mentioned.
Didn’t realize this was your video professor! Maybe you should do your own video? Thanks for coming by ! But no thanks on the lecture…
I do hear you, but I think the info is all in good faith, just adding to the video in the commentary section, like anyone is allowed to do, unless the comments are disabled. I wouldn't have taken offence if I did a video without explanation. Everyone's contribution is good I feel and creates a community spirit. @@juliedunken1150
Thank you. Salt of the earth and light of the world does make sense now.
That was really interesting!! Thanks for sharing this.
Fascinating... I have seen this technique used for arc welding... almost like the salt water solution servers as a sort of capacitor to store energy and release it at the contact transience...
What if air acts as a sort of capacitor to store energy and release it the same way, but not as efficient as salt water?
@ syed adnan
Hi, for a scenographic effect appreciable it takes a voltage of 230 volts and a minimum load of 300-500 watts..
it's AC or DC ?
DC ;)
+Petardo238 it's not working
It's not working
Can you plz tell me the names of the materials..... We're doing it for science fair 😋
I saw this on the Internet before...besides, the technique of this experiment and the brightness of the bulb is super cool! Metal and salt water is a conductor of electricity..
Great experiment, interesting how much heat is generated by an arc. It melts the iron very quickly.
Hi Ray, even your experiment melted copper ;)
"Electric Experiments"Roobert33
Yes it did, my current was a bit higher than 2.2 Ampères.
Guys the chemistry behind that is quite simple.
NaCl is dissolved in H2O...red wire is the anode and black
is the cathode which leads us to following half reactions:
Anode: 2 Cl- __to__ Cl2 + 2e-
Cathode: 2 H2O + 2e- __to__ H2 + 2OH-
Overall reaction: 2Na+ + 2Cl- + 2H2O __to__ Cl2 + H2 + 2Na+ + 2OH- (dissolved Sodium hydroxide_NaOH)
So the evolving gases are H2 and Cl2, BUT: since the
products of the reaction are not separated by a membrane, the Cl2 gas reacts
with 2OH- to form OCl- (Hypochlorite) + Cl- + H2O
Thus it is somehow dissolved Sodium Hypochlorite (NaClO)
Thank me later...
Aww.. I have forgotten to mention that O2 is NOT evolved
since the oxidation potential of Cl- comes first, so Cl2 is formed. To form O2,
all Cl- have to be removed by gaseous Cl2. But things get complicated as Cl2 is
not only removed but also reacts to Chlorites which are soluble in water. So
ClO- is involved, possibly also chlorates and perchlorates which makes it hard
to remove chlorine from the water.
Beautiful demonstration! Now I will look an see if you have anything on cavitation!
He explained without even opening his mouth for me good channel
جاي من عند مستر محمود مجدي
مستر محمود بيمسي عليك يا ريس😂😂
That is so freekin cool !
That was pretty amazing
thank you, I was wondering if I could use salt as an alternative to hydrogen sulfate, well I guess I can, so thanks for making this video
Thanks for the great rheostat video. Do you have any experiment with similar apparatus such as a light bulb; but NO source of AC or DC power?
Gort Sneeley I have planned something you say, as soon as possible I will make a video.
احسنت عاشت ايدك صح بدون كلام بس فعل👌 اخوك من العراق🇮🇶
This guy seems to be a welder at heart. I wonder if this setup can be used as a cheap (although dangerous) arc welder. Amperage could be adjusted with different light bulbs.
It’s really easy but it’s not how you think it works
Pure water (distilled) is a very poor conductor of electricity. That good ole salt always does the trick. TDS(Total Dissolved Solids) meter work by testing the conductivity of the water. no conductivity, no dissolved minerals/solids. Good conductivity , lots of dissolved solids. Now you know why sweaty hands conduct so well. Nice video.
Alkaline water is the best
Will the water getting hot eventually? And evaporate?
@@Lovemyfriends1 Alkalis are water soluble and they obviously conduct electricity
caption should have been that salt water is a good conductor of electricity.
That doesn't make it an experiment idiot. It is an experiment and you don't name an experiment with a conclusion
Janith Oshadha you don’t need to call him an idiot
@@zahra-bs2pz and you don't need to point that out XD
Why is it a good conductor of electricity? Salts barely dissociate in water because they contain weak bases and acids so I’m a bit confused because they should have few ions in the solution????
Thank you to give a new information
Can you post a video of the same experimentation without connecting cables with the voltage counter device?pls.
Exactly
I was thinking the same thing.
I had made this experiment on a video i have on CZcams in late 2012 using 230v AC and an 100w light bulb.
At least with resistive loads it works as good on AC as with DC although it has much higher resistance than a copper wire to power any actual load with it,it also makes Chlorine and Hydrogen gases so the experiment must be reproduced in a well ventilated area.
+truebassB Yes, in fact. well ventilated.
What is the Hz thing you are plugging the wires into? Is that needed or is it just for measure output?
A very good experiment on IONIC HEATING OF WATER
Esto es increíble.
Con razón dicen que nosotros somos la sal. ~.~
This is incredible. Rightly they say that we are the salt. ~.~
+Alba Reyes Estoy de acuerdo
Regular water = Insulator, Salt water= Conductor. He made a path. Is pretty much what this video is.
I thought water is a conductor. Like don't drop a lamp in your bath with you in it.
Mrlr J it's not 100% conducter or 100% not conducter
Guy's what are the tow type of iron in it.
Plz tell
that's nice
Very good idea thanks for sharing.
It was a fantastic video
Electric Experiments Roobert33,
I have a question, I can see that on the bottom part of the bulb it connects to the wire. I would like to know how do you connect those wires to the bulb to make the two poles of the circuit (the positive pole and the negative pole).
I am studying your experiment because I want to implement in one of my projects and I do have all the equipment, but the bulbs that I have they are regular lamps. It has that metallic bottom to cover the wires I guess and I was wondering how I would be able to separate it. I understood how your experiment works and how it's done, but I still have this doubt of how to connect the positive and negative poles.
Thank you
Raffael Rabelo A nail goes to the wire leading to the light bulb, the other wire is connected to the transformer, look closely at the video ..
Robert 33 you pretty much created a switch of saltwater, that provides energy to right?
The machine where the wires are initially plugged,what´s the name of that machine?
He didn't create a switch. Electricity is the movement of ions.
He added distilled water at first(not tap water otherwise it would have conducted electricity), then afterwards he added salt(table salt), the salt dissolves as ions in the water. Now the water conducts electricity.
Also, the machine in which he plugs in at first is the source (AC maybe), it provides different voltage for different slots.
Con ese mismo modo se puede hacer una pequeño soldador de arcos eléctricos ...para soldar con electrodos finos...se logra una soldadura perfecta... y muy resistente...
Its really amazing 👌👌👌👌
You see bubbles. If I am not mistaken, the current is splitting water into H & O. Your experiment is 2 in 1 :).
Your kidding right? You cant split water back into hydrogen and oxygen, brush up on your laws of thermal dynamics'
Thats chlorine and hydrogen. It is as same as Chlro Alkali process.
@@brandonjohnson1611 I like how you sound so sure of yourself and telling others to brush up on the laws. When in fact you are so wrong! You can most certainly split water into Hydrogen and Oxygen. Maybe you should brush up.
amazing
هل انت صيني
wow this was a really cool experiment
+Adrian Ciemniecki just that i didnt try it with 250 volts... XD lol
Woah. What a large light source. Anyway, extra excellent work.
Just to get a quick chemistry lesson in for myself, what causes the water to turn yellow? Is it a chemical reaction? Or just just residue from (what looks like) the nail carrying the negative charge? Or am I just way off? Lol
Trint
It turns yellow for a chemical reaction..
TheDirtyTexan this light lamp that's not water yellow
If there is a change of colour or bubles means that a chemical reaction is taking place. In this case you can see bubbles around the nails which is showing that a reactions is taking place generating hydrogen. The second reaction is shown by the change of colour. Water becomes yellow because the sodium is shown in the form of lye.
you tota it's not, when the lightbulb is off, you can still see the yellow water, there is a chemical reaction taking place
TheDirtyTexan
Good
Great expariment
Gf: what are you watching? Me: this guys welding water🤣 wait what??
Whoaaa!I just thought the bulb will explode.
why there is dislike ? awesome vid
Oh my god
Nice experiment
this is a super idea
so wat is the use of the saltwater if u still connect the circuit with a 240V power supply on the far left ??
+The Honcho of All Spearheads salt is needed to close the circuit
Vision kay, thx for clearing me up!
correct coment
I thought it's a common knowledge.. ．−．
OMG DA WATERS SOOOOOOOOOOO SALTY I LUV IT MAN GIMME MORE M8
Nice !
so, we can make a high power potentiometer using salt water, cool
Hey can u tell me the things need to do these becouse i have a project like this in chimestry!
Salt,water,mentol,brain!!!
@@vimalvimal324 😂
Brain 😂 yes correct
I was just reading about icon bonds in my textbook. It mentioned that solutions containing dissolved ions are electrolytic, and that the polarity of water interferes with ionic bonds. So... I went to check for a CZcams video of this and voila!
+Adam Simonini salt can generate electricity ?, it is just a conductor isn't it ?
I regret that I didnt take this stuff seriously in high school, now Im clueless in university
Well that was pure awesomeness...can u answer my question - can salt water amplify electric current?
مين تبع محمود مجدي 😂
From now on I'm gonna eat more salty and I will become so powerful
haha
With high blood pressure for sure.
I want to get powerful too, so from now on I'm only going to drink salt water.
@@masterclickbater6055 What the.. It's super dangerous!

okay this amazing i can't hold my tears
We are doing this project 😂 #fun

hey i have one more question
How does this apply to the real world?
i dont fucking know maybe better technology for your ungrateful ass who is apparently using a phone. you asswipe wont be able to even use a phone without science and technology

This is great . But is there no risque to get Cl2 which is deadly gaz
That is crazy awesome
This experience show how salt water conduct current not produces energy.
It is possible though to use salt water to create electric current.u just have to have a piece of copper and a zinc washer to create a chemical reaction
hi thes is normal salt i mian salt for eat it is

I watch this video with my son,we both think it crazy and funny.
imagine if a large iceberg breaks off and melts rapidity in warm sea water. it might have some dis charging effects under water lighting
desconnect the red wire. pls light off
right
Hahaha
brotherly advice only..first this makes unsafe for the guy playing with rod. it's makes no sense how could you light a bulb without AC/DC? anode is connected to the positive side of the bulb then you used a liquid with added salt as a conductor for cathode then the incandescent lights on. this makes your life complicated why don't use a real conductor for the cathode. this does not prove anything as you are creating an arch flash that may endanger your life and the other person besides you. you may use all forms of conductivity such as: silver,copper,gold,aluminum,iron,steel,brass,bronze,mercury,graphite,dirty water,even concrete and also your body to light up the incandescent bulb with AC/DC. Materials with high electron mobility are called conductors... So be safe in doing such experiment..
yes right
LMAO. You mean he shouldn't use this in production?
This is not DC Voltage it's AC voltage, as DC does not oscillate as shown by the Hz meter . Other than that pretty cool experiment. Oh the bubbles are HHO gas and is highly explosive in large quantities, so no letting this gas get to thick, sparks around this will cause it to ignite, so do it in a well ventilated area. Best Wishes and Blessings Keith.
They should teach this in school in case we lost at sea or an island
HE'S GOT VOLTAGE COMING FROM THE THING IN THE BOX WITH METER AND USING THE WATER LIKE A SWITCH
Awesome Bro Awesome
So how come when jelly fish shocks you the ocean nearby doesn't shock other people as well? Beautiful video!

Can you please take this to the government it can help south Africa so much
Very good
So basically they're just rusting the iron nail at a pretty fast rate aka hydrated Fe2O3, FeO(OH), and Fe(OH)3

How does this affect boaters in salt water marinas? Does it affect the metal props, shafts, etc?
Salt water conducts electricity. Bravo
Would you know how to calculate the resistance of a distilled water mixed with salt? How can I reach a certain resistance in a solution of salt and distilled water?
very good idea
woooahh amazing
I hope people that lives in dead sea would make like such thing like this
should i try it at home?
I LOVE SCIENCE
Salted water is acting as conductor, and behaving as a switch only. The impression is given that the electricity is being produced from salted water. Behind there is a voltage source and salted water is in series to the load.
I see the DC generator, where dp you find that equipment ? alsi does it work to AC too ?
You just gave me a new idea to make something
Great scott marty
The same thing happens to some extent in our bodies. Salt is vitality
What's the name of the device you connected the red & black wire to?
super fantastic ayyayayya
is that just a salt? how it can be?! wonderful
nice I remember this from scholl we make all kind experiments with Salt Water Egg Experiment
