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.

Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.

Solution

The correct option is A
Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.

Copper from the copper sulphate solution will be deposited on the carbon rod. When the electric current is passed through the copper sulphate solution, copper sulphate dissociates into copper and sulphate. The free copper gets drawn to the electrode connected to the negative terminal of the battery, i.e. carbon rod and gets deposited on it. Thus will obtain a coating of copper on the carbon rod.
