When a lead storage battery is discharge...

When a lead storage battery is discharged :

A

`SO_2` is evolved

B

lead sulphate is produced at both electrodes

C

sulphuric acid is consumed

D

water is formed.

Text Solution

Verified by Experts

The correct Answer is:
B, C, D
at anode : ` Pb_s + So_(4(aq))^(-2) + 4H^(+) + 2e^(-) to PbSo_(4(s)) + 2H_(2(l)o)`
overall reaction : `Pb_s + Pbo_2 + 2H_2SO_(4(aq)) underset("Charging")overset("working")iff 2PbSo_(4(s)) + 2H_(2(l)o)`
