copper acetate - the best way

[jamit37]

Does anyone have any experience making copper II acetate? I can think of two ways.

the first way is to react copper II carbonate with white distilled vinegar but that is going to require alot of vinegar.

the second way is to react ammonia solution with copper sulfate and then add some sodium hydroxide followed by

vinegar. Does anyone have other suggestion that might give a good yield?

All the acetate ions in the product will come from vinegar whichever way you do it, so you will need a lot of vinegar.

Your "second way" doesn't make sense.

 

If you add dilute sodium hydroxide to a solution of copper sulphate you will get a precipitate of copper hydroxide. You can wash that with water and dissolve it in vinegar to get copper acetate or you can treat the copper carbonate with vinegar to get copper acetate.

Adding ammonia won't help.
