I like all the compounds of Copper (Except the really poisonus ones lol) but I was wandering if anyone knew how to produce some of these compounds. If it is reacting the acid with the metal can someone tell me how to get rid of the remaing acid while producing the compound. (Please no safety warnings)
The place to start is reaction of copper metal with nitric acid. This produces copper(II) nitrate. Crystallize the finished product from water. This gets rid of excess HNO3. Add Na2CO3 to a water solution to produce basic copper carbonate [CuCO3*Cu(OH)2]. Add various acids to this to make cupric acetate, copper sulfate, etc. Finally, add concentrated ammonia to a CuSO4 solution and evaporate and crystallize an electric blue preparation of Cu(NH3)4++SO4=.
Copper hydroxide will react with most acids to give the salt. Don't get too hot or copper oxide may be formed which is less reactive. If you use an excess of copper hydroxide it can be filtered off the salt solution and you will not have any free acid. Then evaporate off water to concentrate the solution to point of crystalisation.
