Solution

The correct option is A True
Reduction always takes place at the negative electrode (cathode). $C u^{+ 2}$ ions, present in the solution, get reduced to $C u$ at the plate connected to the negative terminal of the battery.

Fill in the blank.

If you pass current through copper sulphate solution, copper gets deposited on the plate connected to the _________ terminal of the battery.

Q. When electric current is passed through the copper sulfate solution, free copper ions gets drawn to the electrode connected to the .............. terminal of the battery and gets deposited on it.

A beaker contains an acidified copper sulphate solution. A copper plate and a carbon rod are kept in this copper sulphate solution. The copper plate is connected to the positive terminal of a battery whereas the carbon rod is connected to the negative terminal of the battery. What will you observe when an electric current is passed through this set-up for a considerable time?

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.
