In the discharged state, both the positive and negative plates become lead(II) sulfate (PbSO 4), and the electrolyte loses much of its dissolved sulfuric acid and becomes primarily water. Negative plate reaction Pb(s) + HSO 4(aq) → PbSO 4(s) + H (aq) + 2e The release of two conduction electrons gives the lead electrode a negative charge. As electrons accumulate, they create an electric field which attracts hydrogen ions and repels s
