ANSWER

A galvanic cell is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell. It generally consists of two different metals connected by a salt bridge or individual half-cells separated by a porous membrane. Daniel cell is a galvanic cell.

Zn(s)+Cu

2+

(aq)→Zn

2+

+Cu(s)

This reaction is a combination of two half reactions whose addition gives the overall cell reaction:

(i) Cu

2+

+2e

−

→Cu(s) (reduction half reaction)

(ii) Zn(s)→Zn

2+

+2e

−

(oxidation half reaction)

The reduction half-reaction occurs on the copper electrode while the oxidation half-reaction occurs on the zinc electrode. These two portions of the cell are also called half-cells or redox couples. The copper electrode may be called the reduction half-cell and the zinc electrode, the oxidation half-cell. In Daniel, cell Zinc acts as an anode and copper act as a Cathode
