The basic copper sulphate is an electrolyte, and the anode copper element loses electrons into the solution, and the copper ions in the solution are reduced at the cathode to form a single element of copper attached to the surface of the cathode, thereby achieving the purpose of electroplating. The whole process theoretically says that the copper ions in the solution are not lost, are obtained from the anode, are lost at the cathode, and the electrolyte increases the concentration of copper ions, so that the electrolysis proceeds more quickly.
As for sulfuric acid, since basic copper sulfate is a strong acid weak base salt, it is easy to hydrolyze to produce copper hydroxide precipitate and lose copper ions. The addition of sulfuric acid can prevent hydrolysis of basic copper sulfate and improve the utilization rate of raw materials.
