Converting Copper sulfate


Recommended Posts

People,

Have some cupper sulfate pentahydrate, wanting to concert it to the chloride. Aqueous solution for is OK. Can I just add an excess of conc HCl to the solution of the sulfate? Then crystalize the chloride and wash off the sulfate solution? 

 

Thanks.

Which one? There are two CuCl and CuCl2 ...

https://en.wikipedia.org/wiki/Copper(II)_chloride

Is it your aim? or just playing for fun?

"Copper(II) chloride is prepared commercially by the action of chlorination of copper. Copper at red heat (300-400°C) combines directly with chlorine gas, giving (molten) copper (II) chloride. The reaction is very exothermic. Cu(s) + Cl2(g) → CuCl2(l)"

CuCl is easy. Add sodiumchloride or hydrochloric acid and a strong reducer like dithionite or Ascorbinic acid to the coppersulfate. You will get a white precipitate.

Manganesechloride : Add sodiumhydroxide first to manganese sulfate , you will get a sludge of manganese hydroxide. Filter it and wash it. Then neutralize with hydrochloric acid.

Thanks, Chen! That seems easy for me to do (for the Mn Cl). I dont have any of those reducers around though for the Copper chloride. But at least I got one of those taken care of! Thanks again!

Goofy website useage- I click quote and difficult to know where to type, then I end up with 2 quotes. I will learn eventually, I guess.
