Question:medium
In a lead-acid battery, if 1 A current is passed to charge the battery for 1 h, what is the amount of PbSO$_4$ converted to PbO$_2$? (Given data: 1 F = 96500 C mol$^{-1}$)

Show Hint
Faraday's first law: Amount of substance $\propto$ Total charge. Remember to check the oxidation state change to find '$n$' (for Pb, it changes from +2 to +4, so $n=2$).
