Question 1

O2(g) + 4 H+(aq) + 4 e- → 2 H2O(l)

E° = +1.23 V

Pb2+(aq) + 2 e- → Pb(s)

E° = -0.13 V

2 H2O(l) + 2 e- → H2(g) + 2 OH-(aq)

E° = -0.83 V

Based on the half-reactions above, electrolysis of an aqueous solution of Pb(NO3)2 is expected to produce.
◦ O2 at the cathode and Pb at the anode.
◦ Pb at the cathode and O2 at the anode.
◦ H2 at the cathode and Pb at the anode.
◦ Pb at the cathode and H2 at the anode.

Question 2

The chlor-alkali industry is based on the electrolysis of aqueous NaCl. What are the products of this electrolysis?
◦ NaOH, H2, and Cl2
◦ NaOH, O2, and Cl2
◦ Na and Cl2
◦ NaOH, H2, and O2
