Which of the following reactions occurs at cathode during charging of storage battery ?

A

formation of `PbO_2`

B

formation of `PbSO_4`

C

reduction of `Pb^(2+)` to Pb

D

decomposition of Pb at the anode

Text Solution

Verified by Experts

The correct Answer is:
C
During charging , `Pb^(2+)` ions of `PbSO_(4)` are reduced to Pb on cathode .
`PbSO_(4) (s) + 2e^- to Pb (s) + SO_(4)^(2-) (aq)`
