During electrolysis of copper sulphate solution, the positive _ ions accept electrons and get deposited at the _ electrode.

Open in App

Solution

During electrolysis of copper sulphate solution, the positive copper ions are attracted by the negative terminal where they accept electrons and get deposited on the negative terminal.

Hence, the mass of the negative electrode increases while that of the positive electrode decreases.

Q. During the electrolysis process 4 A electric current flows through a copper sulphate solution for 5 mins. Determine the number of copper atoms deposited at the cathode.

Assertion: Upal observed that copper is deposited on the negative electrode connected to the terminal of the battery. Kavya performed the same experiment but she replaced the copper electrode with a carbon electrode and still observed copper is deposited over carbon rod.

Reason: Copper sulphate solution dissociates into copper and sulphate ions when electricity is passed through dilute copper sulphate solution and this free copper ions deposit on the carbon rod.
