how to make copper hydroxide (electrolysis methode)

[diegonikki]

u actually can use any electrolyte even sodium bicarbonate or sodium chloride for this

[demnlordd666]

ok so after some research it is highly suggested but not confirmed by me yet, that electrolyzing a dilute solution of baking soda ( sodium bicarbonate ) with copper electrodes is better than epsome salt, because with MgSO4 it is hard to filter out unless you have a vacume pump. & if you try to boil you will find that a sat sol of MgSO4 has large forcefull bubbles and when done the Cu(OH)2 is full of MgSO4, but with bakingsoda verry little is left in and it is easier to boil off.

[demnlordd666]

by the way i had way better luck squeezing the water out of it rather than any kind of gravity filter. left it for hours and barely any water passed through. so I decanted the liquid off the top and pour the concentrate into a paper towell like a funnell. then I folded the top closed and squeeze the water out. you can dry a large batch to a blue paste quick like this. u still have to finish dry it and powder it but at least it is managable as a paste. thanks for the vid worked great

[funguyround]

what can copper hydroxide bused for?

[maxxorid1]

can u do a remake of sodium hydroxide

[thegodofchemistry]

what will happen if i use sodium chloride

[aten747]

Will this work using salt (NaCl) rather than magnesium sulfate? And what us CuOH used for?

[99Chemicals]

I thought that with a MgSO4 elctrolite it will make copper sulfate and magnesium hydroxide which is insoulble

Cu + MgSO4 + 2 H2O → H2 + CuSO4 + Mg(OH)2

Thx

[g3ov4n12]

"Simple" is to add ammonia or sodium hydroxide to a copper sulfate solution. No need for electrolysis. With the copper hydroxide precipitate you can make copper oxide (CuO) for copper thermite.

[PyroAbsestion22]

i know that the power supply is 9v but how much is the mA(miliamps)?

[koolness73]

so what would i have to do to sever the ionic bonds between magnesium sulphate to achieve 2 individual chemicals?

[koolness73]

ps where di you get the copper electrodes?

[TheChemlife]

@koolness73 they're just to plates of copper i got off a construction site

[koolness73]

@TheChemlife ty

[koolness73]

and also with the electroylsis do you just plug it into the houses electricy

[TheChemlife]

@koolness73 ya

[koolness73]

wouldnt this achieve two different chemicals just magnesium and sulphur chemlife?

[TheChemlife]

@koolness73 no. it doesnt' work like that

[koolness73]

but isnt electroylsis meant to sever the ionic bonds and make magnesium and sulphur instead of copper hydroixe?

[PsychoScientist007]

Well I think we don't need magnesium sulfate necessarily to start electrolysis we can add little bit lemon juice and table salt and it will work though not as efficiently as it works in your one process but it will work anyways

[matthew1198765]

can you use sodium bicarbonate instead of magnesium sulfate? I accidentaly produced a blue liquid while performing electrolysis on a sodium bicarbonate solution and im wondering if it is copper hydroxide, copper sulfate, or something else

[TheChemlife]

@matthew1198765 im not sure. i don't know the reaction off the top of my head but what u can do is repeat the experiment and then boil off the water and see what your left with. then test the water for various things.

[hawk1buster]

So this is copper lye?

[TheChemlife]

@hawk1buster sort of? lye is sodium hydroxide. to my knowledge no one calls any of the other hydroxides lye. for example potassium hydroxide would is called potash if you are making soap.

[starshock01]

how does this not make copper sulfate and magnesium hydroxide?

[potts7worth]

@starshock01

that's what I was thinking.

TheChemLife, can you clear this up for me? I'm still somewhat of a chemistry noob

[TheChemlife]

@potts7worth the magnesium sulfate just acts as an electrolyte because the ions it forms in solution are less reactive than the water itself and the copper electrode so instead of forming copper sulfate it just allows copper hydroxide to be formed. this would work with no electrolyte at all but the magnesium sulfate speed up the process

[Lexnd]

is that pure dry copper hydroxide made in this video??

[alewisgb]

can you make it buy connecting two pieces of copper to a battery charger and putting both the cathode and diode in salt water then filter it...

[TheChemlife]

@alewisgb well yes and no, but mostly no. what would happen is chlorine and hydrogen would come off leaving a solution of sodium hydroxide and some copper hydroxide. magnesium sulfate is super easy to get, it's sold in every drug store and some grocery stores. if you're gonna try this, just get some it's cheap.

[alewisgb]

@TheChemlife ok ive started to make it its pretty hummm! promising... the substance was greeny-bluey and when heated to 200 centigrade it turned black, i think it was decomposing into copper oxide... (thats what i want to make, as a final product)

[Digadogup]

HHHHHHHHDDDDDDDDDDDDDDDD

[coolsciencetech]

This is true. I just was wondering because on the industrial scale this is how copper sulfate is made. Perhaps at higher energy levels, the products change.

[TheChemlife]

@coolsciencetech mhm but you need massive amount of power and a much diffrent setup

[hobomnky]

@TheChemlife is the magnesium sulfate just to make it more conductive?

ive dont this b4 with just water and it starts off looking like urs, then it turns very dark brown almost black, assuming it turned to copper II oxide, i was originaly making it to decompose it by heating to make copper oxide but i used the black stuff from the electrolysis and it worked pretty well for thermite, so im assuming it was CuO

[TheChemlife]

@hobomnky unless you use distilled water that will happen. what's happening is your also reacting contaminants in the water so that's the cause of the black stuff. i've done this with tap water and gotten at least 12 different colors

[hobomnky]

@TheChemlife but how come it always starts off as light blue geletin then it all that is visible after the change is black/brown stuff

[TheChemlife]

@hobomnky im not entirely sure but it always happens if there's impurities. i did that with tap water maybe 20 times before i realized the tap water was the problem. it was about the same time that i started doing it properly that i got my lab so it was also easier to do

[gehtomacgyver]

@coolsciencetech copper sulfate is made with about same power and H2SO4 with copper as your electrodes .

[coolsciencetech]

Wouldn't it create copper sulfate?

Cu + MgSO4 + 2 H2O → H2 + CuSO4 + Mg(OH)2

[TheChemlife]

@coolsciencetech logic says it should but it doesn't because hydrogen and oxygen are coming off the electrodes not magnesium and SO4 the magnesium sulfate just acts as an electrolyte to allow the copper to go into solution and bond with the HO gas. at no point do the copper and sulfate ions react

[TheChemlife]

@coolsciencetech also copper sulfate is a very dark blue this is light blue green and copper sulfate is water soluable, this isn't

[Digadogup]

@TheChemlife i think it can depend on the way you use the electrodes

and also if you electrolyse sulfate doesn't it also make sulfuric acid?

correct me if Im wrong always willing to learn.

if u electrolysis copper sulfate, sulfuric acid is made

[TheChemlife]

@Digadogup yes if use electroliys copper sulfate sulfuric acid is formed

[Digadogup]

@TheChemlife some retard left a car battery out side my house >.> so i have 2 litters of it now i made copper sulfate yesterday so ill crystallising it now :)

thank god for lazzy idiots dumping batteries illegally.
