Q. What is the cell reaction occurring in Daniel cell (Galvanic cell)?
J & K CET
J & K CET 2006
A
$ Cu(s)+ZnSO_{4}(aq)\to CuSO_{4}(aq)+Zn(s) $
B
$ Zn(s)+CuSO_{4}(aq)\to Cu(s)+ZnSO_{4}(aq) $
C
$ Ni(s)+ZnSO_{4}(aq)\to NiSO_{4}(aq)+Zn(s) $
D
$ 2Na(s)+CdSO_{4}(aq)\to Na_{2}SO_{4}(aq) $ $ +\,Cd(s) $
Solution:
In Galvanic cell (Daniel cell) the electrical energy is produced from chemical reactions.
or $ Zn(s)+CuSO_{4}(aq)\to Cu(s)+ZnSO_{4}(aq) $
