Explanation:

(a) Most liquids that conduct electricity are solutions of acids , bases and salts.

When an electric current passes through a solution, the solution decomposes into its positive and negative ions. This process of decomposition of the solution is a chemical effect.

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 get attracted towards the plate which is connected to the negative terminal of a battery.

The process of depositing a layer of any desired metal on another material by means of electricity is called electroplating.
