What is the cell reaction occurring in Daneill cell (galvanic cell) ?

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)`

Text Solution

Verified by Experts

The correct Answer is:
B
InDaniel 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.
