Explanation:
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.
Daniel cell has Zn as anode and Cu as cathode. The reactions of Daniel cell are,
At anode(Oxidation),
Zn(s)→Zn
2+
(aq)+2e
−
At cathode(Reduction),
Cu
2+
(aq)+2e
−
→Cu(s)
Hence overall reaction is,
Zn(s)+Cu
2+
(aq)→Zn
2+
(aq)+Cu(s)
Here the chemical energy is liberated when the redox reaction takes place in the cell and it is converted into electrical energy.
