Question

ON PASSING ELECTRICITY THROUGH COPPER SULPHATE SOLUTION​

Answer 1

In a copper sulphate solution, we see that when an electric current is passed it dissociates into copper and sulphate ions. The copper gets deposited on the electrode which is connected to the negative terminal of the battery. From other electrodes, equal amounts of copper are dissolved in the solution. Hence, the loss of copper is restored from the solution and the process continues. The transfer of copper takes place from one electrode to another electrode.

When an electric current is passed through the copper solution, the copper sulphate dissociates to give copper ion and sulphate ion.

(a) copper sulphate dissociates.
