A car battery produces electricity because of the reaction
between electrodes made from Lead (IV)
Oxide and Lead metal, in
the presence of concentrated Sulfuric
Acid. The most common natural failure mechanism in
the battery is the build up of
the insoluble product, Lead
(II) Sulfate, which eventually creates a short circuit
between the electrodes.
PbO2 (s) +
Pb (s) + 2 H2SO4
(aq) ---> 2 PbSO4
(s) + 2
H2O (l)
Suppose that 85.7 grams of Pb reacts according to this
reaction. How many grams of PbSO4 is
formed?
