Solution

The correct option is B copper
When an electric current is passed through the copper sulphate $(C u S O_{4})$ electrolyte, it dissociates into copper $(C u^{2 +})$ and sulphate $(S O_{4}^{2 -})$ ions. The copper ions are drawn to the electrode connected to negative terminal of the battery and are deposited on it.

If plus sign (+) denotes the positive electrode and minus sign (-) denotes the negative electrode, then which of the following statement is correct for an iron spoon to be copper-plated ?
(a) Iron spoon (+), copper plate (-), Iron sulphate electrolyte
(b) Iron spoon (-), copper plate (+), Iron sulphate electrolyte

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.

During copper plating, ions from the electrolyte are drawn to the negative electrode and are deposited on it.

The correct option is B copperWhen an electric current is passed through the copper sulphate (CuSO4) electrolyte, it dissociates into copper (Cu2+) and sulphate (SO2−4) ions. The copper ions are drawn to the electrode connected to negative terminal of the battery and are deposited on it.
