RECHARGING A LEAD ACID STORAGE BATTERY

| A
Lead Acid Storage Battery is made by submerging the two lead (IV) oxide
plates into a 6 molar solution of sulfuric acid. By submerging the two plates
it forces the PbO in one electrode to be reduced, simultaneously the PbO
in the other electrode is being oxidized. Dilute sulfuric acid is a key
component to a Lead Acid Battery. Dilute sulfuric acid functions as the
electrolyte in the Lead Acid Storage Battery. The sulfuric acid, H2SO4 provides
the hydrogen ions needed for the reaction. The electrolyte solution contains
both Hydrogen atoms and Sulfate ions. During the reaction, Hydrogen ions
react with lead (IV) oxide to produce lead (II) oxide and water. |
The
most convenient attribute of the Lead Acid Storage Battery is that its rechargeable.
AN alternator of generator reverses the discharge process to recharge the
battery. The hydronium ions are used up in the discharge cycle, so the acid
concentration decreases. The first reaction forms which when reacting with
water and connected to another Lead Acid Storage Battery, can turn into
lead, lead (IV) oxide and sulfuric acid. Backward Reaction (Rechargable): 2 PbSO4 + 2 H2O ----> PbO2 + Pb + 2 H2SO4 |
