Question

What occurs at one of the electrodes in both an electrolytic cell and a voltaic ccl1?
( I) Oxidation occurs as electrons arc gained at the cathode.
(2) Oxidation occurs as electrons are lost at the anode.(3) Reduction occurs as electrons are gained at the anode.
(4) Reduction occurs as electrons are lost at the cathode.

Answer 1

The answer is (2) oxidation occurs as electrons are lost at the anode. And for the other electrode, reduction occurs as electrons are gained at the cathode.

Answer 2

Answer : The correct option is, (2) Oxidation occurs as electrons are lost at the anode.

Explanation :

As we know that there are two types of cell which are, electrolytic cell and electrochemical cell.

Electrolytic cell : It is defined as the cell in which the chemical reaction occurs by passing of the current from an external source.

In this electrolytic cell, the oxidation occurs as electrons are lost at anode which is a positive electrode and reduction occurs as electrons are gained at cathode which is a negative electrode.

Electrochemical cell : It is defined as the cell in which the chemical reaction occurs with the production of electric potential difference between the two electrodes.

In this cell, the oxidation occurs at anode which is a negative electrode and reduction occurs at cathode which is a positive electrode.

Hence, the correct option is, (2) Oxidation occurs as electrons are lost at the anode
