uses and disadvantages of electroplating?
In the process of electroplating of copper on a metallic spoon, the iron spoon is made the cathode. A thin sheet of pure copper is made the anode. When electricity is passed through the solution, Cu2+ ions move towards the cathode and get reduced to copper metal. This copper metal gets electroplated on the object, i.e., the metalic spoon.
The sulphate ions move towards anode. Here the sulphate ions do not get oxidied. Instead, the copper metal of the anode gets oxidised to Cu2+ ions. These copper ions go into the solution..............
But, why does ths happens? Why does the sulphate ions do not grt oxidised? Instead, why does the copper metal of the anode gets oxidised? Please explain me as fast as possible. I've to give an exam. Hope to get the answer from a MERITNATION EXPERT.
