Multiple Choice
The electrochemical reaction which powers a lead-acid storage battery is as follows:
Pb(s) + PbO2(s) + 4H+(aq) + 2SO42-(aq) → 2PbSO4(s) + 2H2O(l)
A single cell of this battery consists of a Pb electrode and a PbO2 electrode,each submerged in sulfuric acid.What reaction occurs at the cathode during discharge?
A) Pb(s) is reduced to PbSO4(s) .
B) PbO2(s) is reduced to PbSO4(s) .
C) PbO2(s) is oxidized to PbSO4(s) .
D) Pb(s) is oxidized to PbSO4(s) .
E) H+ is oxidized to H2O(l) .
