Question

What is the cell reaction occurring in Daniel cell (Galvanic cell)
A. `Cu_((s))+ZnSO_(4(aq))toCuSO_(4(aq))+Zn_((s))`
B. `Zn_((s))+CuSO_(4(aq))toCu_((s))+ZnSO_(4(aq))`
C. `Ni_((s))+ZnSO_(4(aq))toNiSO_(4(aq))+Zn_((s))`
D. `2Na_((s))+CdSO_(4(aq))toNa_(2)SO_(4(aq))+Cd_((s))`

Answer 1

Correct Answer - B
In Daniel cell (copper/zinc galvanic cell), the spontaneous chemical reaction between zinc metal and aqueous copper (II) sulphate is conducted so as to obtain the available chemical energy released in the form of electrical energy.
