Question

The electrochemical cell stops working after sometime because : (A) electrode potential of both the electrodes becomes zero (B) electrode potential of both the electrodes becomes equal (C) one of the electrodes is eaten away (D) the cell reaction gets reversed

When one compound of in the anode of an electrochemical cell is oxidized, those electrons serve to reduce the compound at the cathode side. When the material at anode no longer has electrons to lose, the reaction stops and cell stops working.

Q. The electrochemical cell stops working after sometime because :

electrode potential of both the electrodes becomes zero

electrode potential of both the electrodes becomes equal

one of the electrodes is eaten away

the cell reaction gets reversed
