Cars are powered by lead-acid batteries and the electrochemical cell
processes are described the following net redox reaction:
Pb(s) + PbO2(s) + 2H₂SO4(aq) → 2PbSO4(s) + 2H₂O(l)
Identify which ONE of the following statements is CORRECT?
O a. Lead as both the metal and in the ionic compound is reduced and
hydrogen is oxidised.
O b. Lead as both the metal and in the ionic compound is oxidised and
hydrogen is reduced.
O c. Lead in the ionic compound is reduced and metallic lead is oxidised.
d. Lead as both the metal and in the ionic compound is oxidised and
oxygen is reduced.
Oxygen is oxidised and lead as both the metal and in the ionic
compound is reduced.
