उत्तर
If you pass current through copper sulphate solution, copper gets deposited on the plate connected to the negative terminal of the battery.
Explanation:
When an electric current passes through a copper sulphate solution, the solution decomposes into positively charged copper ions and negatively charged sulphate ions. These positively charged copper ions are attracted to the plate connected to the negative terminal of a battery.
