- Hello Friends in this video we will make Copper I and Copper II chloride
Both are different in their physical appearance
be safe in home during this pandemic season and try to watch all my videos.
This video has been recorded and edited with much effort and difficulty. Lack of proper equipment and chemicals can make video look unfinished. I request your love and support in donations also.

2:20 instead of metabisulfite,you can use copper metal.the process goes as copper reduces 2+ state to 1+ by taking electrons from CuCl2 and producing CuCl.hope it helps
You could use vitamin C too
@@kenon2414 oh well that's quite considering ..
Very nice video! I had planned to make Cu(i)Cl via the reduction with metallic copper but this method would be so much better. Also the tip for how to store it without it decomposing (which is loves to do when dry) is a really great tip so thank you for sharing!
I dried some CuCl2 to it's anhydrous form then over the day I watched it regain it's colour as it absorbed moisture from the air, it was cool to watch.
Can get copper to go thru a whole bunch of colors by dehydrating or changing the concentration of HCl and/or water in the case of (ii)..
I need (i) for blue flame with methanol... Not as a demo but for a longer burning run... The instability is a problem, as it prefers to be in the (ii) state... The green is pretty but I want the blue 🤣
@@MadScientist267 absolutely, various mixture of anhydrous/hydrate blend make a rang of the spectrum from full hydrate to anhydrous.
That is the worst part, the O2 in the air really like to oxidize the product, then you end up with CuCl2 in approximately half the previous amount and copper oxide.
Thank you - I did a practical with pupils today - 'copper carbonate ' with 1m HCl (aq) - got a lot of brown stuff on the bench - can't figure it out - CuCO3 may have been hydrated!
Awesome video! Thank you for the knowledge.
I think sodium dithionate may also work for CuCl ?
Nice video!
How to refined iron in aquarega?
There's an easier way to do this. Use copper II oxide (CuO), and mix with HCl then filter it. Heat solution to evaporate half the water.
Are you sure copper chloride washed with water then become copper oxide?
Anyone know if this stuff will change the fire purple
Still blue green
If you want purple go for iodine
copper carbonate doesn’t exist in a neutral form, only the (cuoh)2co3 exists, would be nice to see that in the reaction with hcl, and this might have impacted the reaction yield and calculations
actually it does... cuco3 does indeed exists
@@uxleumas not in an aqueous solution, it gets hydrolysed immediately to the basic copper carbonate there
@chu Harry not in the aqueous solution, it gets hydrolysed (and the original comment meant copper basiccarbonate, not copper normal carbonate out of an aq solution in a ion exchange), btw sorry for being a slowpoke
Good vídeo.
Sir could you please explain to me how the copper 1 chloride slowly turns to copper 1 oxide?
Ever best!
Can I use something different than Copper carbonate like copper (ii) hydroxide and if yes do i need to use different quantities of supllies?
Can you use sodium metabisulfate instead?
Sir why did u tell that it is not possible to crystallize the copper 2 chloride from solution? Most salts when brought to a saturated hot solution, cooled then becomes supersaturated and then crystallises out yhe excess salt. Also, copper sulphate makes so beautiful crystals!! Could u please explain me this?
Thank you
@@vibzzlab I've managed to get it "dry" but the deliquescince does make it avoid it. You can see crystalline behavior there but to say its "crystallized" is a stretch
It is a crystal mat by staying to low temperature, like 35⁰c. I set a watch glass on a dehydrator. Still a little amorphous, but the top will be short crystals.
The slower it dries the better to see them. It patterns the surface also like frost, but deeper.
When you dissolve copper II chloride in water, what color is the solution?, blue? I see in all other videos that the solution is blue.
@@vibzzlab Ok. Cool.
@@vibzzlab I guess if you now add some sodium sulphate, the solution should turn green, right?
Why cant the copper II chloride crystallize out?
@@vibzzlab I see.. Thanks!
will sodium bisulfite work?
@@vibzzlabthanks, i got confused, so metabisulfite = 2 dried sulfites?
Can I use 31% HCl? Instead of 36%
@@vibzzlab thanks man, btw love ur videos
