Dear sir, I am wondering if you can answer my question. However, we know that neither copper nor sulphate are blue. I would be greatful if you can send to me the solution as soon as possible. Thank you very much. This sounds like you are asking someone to provide the answers to your homework assignment, Mr. Abdolly.
Copper chloride is also blue.
That was a hint . I was never good at following 'stream of consciousness' writing, and it looks like I still don't have the hang of it. Regrettably, I have little idea what you are trying to say. So, if you dip copper leads which have oxidized, the sulfuric acid will dissolve those copper oxides to become copper sulphate. Nobody can advise the flammability, explosive potential, or other characteristics of a solution which they are not sure the contents of, and which is thousands of miles away.
