Define anode and cathode.

Text Solution

Verified by Experts

Anode is the electrode at which oxidation occurs. It sends electrons into the outer circuit. It has a negative charge and in shown as (-) in cell diagram.
Cathode is the electrode at which electrons at which electrons are received from the outer circuit. It has a positive charge and is shown as (+) in cell diagram.
