Reaction during Charge

When charging, the reverse chemical reaction takes place: 2PbSO4 sol + 2 H2O liq ⟶ Pb sol + PbO2 sol + 2 HSO4−aq + 2 H+aq.

   o Lead sulphate crystals dissolve/(are broken down into) lead dioxide which is deposited on the (+) electrode and lead which is deposited on the (-) electrode. 
   o The electrolyte reverts to dilute sulfuric acid.
