Question

Write the equations for the reactions taking place at anode and cathode in lead storage cell.

Answer 1

Oxidation at anode:

$Pb\left(s\right)+S{O}_4^{2-}\left(aq\right)\to PbS{O}_4\left(s\right)+2e^{-}$

Reduction at cathode:

$Pb{O}_2\left(s\right)+4H^{+}\left(aq\right)+S{O}_4^{2-}\left(aq\right)+2e^{-}\to PbS{O}_4\left(s\right)+2H_{2}O\left(l\right)$
