Copper hydroxide - the electrochemical approach

[kevp951]

Was fur ein toller video !

[PyroAbsestion22]

what other electrolytes could be used besides sodium or potassium nitrate?

could I use Epsom salt (magnesium sulfate)?

[sciencoking]

Sulfate works too, basically any non-halide does (halogens form nasty and useless complex ions)

[mewrox99]

If you leave it out for a while it will decompose to Copper Oxide, it may also absorb carbon dioxide from the air forming copper carbonate

[BogMonkey53]

Brilliant video.

[123samic]

how much sodium nitrate did you use.

[sciencoking]

Was that a question?

I think it was around 8-10g for 300ml

I miss the "original" voice :(

One time I did electrolysis of water solution of NaCl using a copper anode - and surprisely got a copper (I) hydroxide. It has a beautiful orange color.

[sciencoking]

That was mos probably copper-I-oxide or a complex salt. copper-I-hydroxide is very unstable and unlikely to stay stable long enough that you can collect some of it.

[AlexxAXe]

@sciencoking

Maybe. Then I was a schoolboy, and could not analyze the substance. However, after heating it was bright red - the same as iron-III-oxide and copper-I-oxide. I thought it was copper-I-oxide, and an orange substance - copper-I-hydroxide.

Great video sciencoking!

[bionerd23]

you finally started talking, and it's great! \o/

keep it up. ;)

i was trying to make this a while ago to make CuO, but i just tried electrolysis of water with copper anode, which worked well, but after a while i would get a brown material, i was eventually gona put it directly under a heat lamp tp decompose it, but im not sure if the final product is even CuO

help?

[sciencoking]

I was hoping someone would say that:

It doesn't work with sodium chloride, because chlorine produces a crapload rather useless complex ions, which are often hard to separate. Your water probably contained traces of chloride. Add some nitrate to your water and it works 100 times better =)

[hobomnky]

@sciencoking huh? i never said anything abt sodium chloride?lol

i used a very small amount of sodium hydroxide tho (like 2 drops of a weak solution)

[sciencoking]

NaCl is just an example. As i said, it was probably due to a contamination with chloride. I think i have to try it with chloride too, though.

Very good well narrated video

[123samic]

what kind of cathode did you use,and will a 6 volt battery work.

and great video

[sciencoking]

I'm not even sure what my cathode is made of 0o

I think it's stainless or chomium plated steel. As I said, everything will work, copper too, of course =)

6 volts is very good. My solar cells reached 3 volts.

[123samic]

@sciencoking thanks

[Kendrana]

Nice video.

Interestingly, I made Cu(OH)2 [and probably CuCO3 too] yesterday through electrolysis.

Also like the fact that you're gonna narrate your videos! I hope you'll post more frequently now. :>

[hkparker]

Very comical and well explained, great video!

[Phacias]

Chemistry and ecology AND electricity in ONE video. I love You <3

;D

[TheRolemodel1337]

lmao at 0:42 XDXD

gimme that electron!

lol fuck you XD

well why should i unsubscribe to your channel?

thaere is no reason to unsubscribe to a channle even if it inactiv

[AScannerClearly]

Nice to see you making videos again! Very interesting, what voltage do those photovoltaic cells give you? And what other things can you make with the copper hydroxide? I just recently got some KNO3 so I may give this a try.

[sciencoking]

The panels put out 18 to 20 volts, but as the cell has a really low resistance, it drops to less than 3 volts. Off camera, I added my other selfmade panels (you might know them from my old hydrogen videos) and I got up to 3.4 volts@ 2 amps.

Copper hydroxide is good for making various copper salts such as copper acetate, chloride, nitrate, sulfate and many others. When heated, it decomposes into copper(II)oxide, which is useful if you want to make death thermite. I might try this too :3
