The cell diagram for the lead-acid cell that is used in automobile and truck batteries is
Pb(s)|PbSO4(s)|H2SO4 (aq)|PbO2 (s), PbSO4(s)| Pb(s)
The comma between PbO2(s) and PbSO4(s) denotes a heterogeneous mixture of the two solids. The right-hand lead electrode is nonreactive.
Write the balanced equation for the net cell reaction.
equation:
Look up standard potentials for the oxidation and reduction half-reactions, and then calculate the value of E°cell .
E°cell = V
Calculate the value of ΔG° rxn.
ΔG° rxn = kJ.mol-1
Calculate the value of Ecell at 25°C if [H2SO4] = 10.0 M.
Ecell = V
How many lead-acid cells are in a 12 V car battery? Round to the nearest integer. number of lead-acid cells:
♦ Relevant knowledge
The lead-acid battery was the first battery that can be recharged invented. It was developed by French scientist Gaston Plante in 1859. The anode of a lead-acid batteries is comprised of porous lead , while the cathode is made from lead oxide. Both electrodes are submerged in an electrolytic solution consisting of the sulfuric acid along with water.
