Verified by Experts

Galvanic cell is an electrochemical cell that converts the chemical energy of a spontaneous redox reaction into electrical energy. It has an electrical potential equal to 1.1 V. In galvanic cell, oxidation occurs at anode and it is negative plate. Reduction occurs at cathode and it is positive plate.
The two half-cell reactions are
(i) `Cu^(2+) + 2e^(-) rarr Cu` ( reduction half reaction )
(ii) `Zn(s) rarr Zn^(2+) + 2e^(-)` ( oxidation half reaction )
