Solution

The correct option is A copper ion and sulphate ion
When electricity is passed through the copper sulphate solution, copper sulphate dissociates into copper ions and sulphate ions. The copper ions move towards the electrode connected to the negative terminal of the battery (cathode) and get deposited on it.

Hence, option $B$ is correct.

When current is passed through Copper Sulphate solution, Copper sulphate dissociates into copper and sulphate.This free copper deposits on one of the electrodes.What about the loss of copper in the solution?

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.

When an electric current is passed through a solution containing copper sulphate, copper gets deposited on which electrode?
