During discharging of a lead storage battery

A

The reaction at anode is `Pb rarr Pb^(2+)+2e^(-)`

B

The reaction taking place at cathode is
`Pb^(2+)+2e^(-) rarr Pb`

C

The overall reaction is
`Pb+PbO_(2)+4H^(o+) +2SO_(4)^(2-) rarr 2PbSO_(4)+2H_(2)O`

D

The reaction taking place at cathode is
`PbO_(2)+4H^(o+)+2e^(-) rarr Pb^(2+)+2H_(2)O`

Text Solution

Verified by Experts

The correct Answer is:
a,c,d
Cathode `:PbO_(2)(s)+2e^(-)+4H^(o+)(aq)+SO_(4)^(2-)(aq)rarr PbSO_(4)(s)+2H_(2)O(l)`
Anode `: Pb(s)+SO_(4)^(2-)(aq) rarr PbSO_(4)(s)+2e^(-)`
