What substance are found at the anode and cathode when sodium chloride calcium chloride and lead oxide are electrolyted?

During the electrolysis of sodium chloride (NaCl), chlorine gas is produced at the anode, while hydrogen gas is released at the cathode. For calcium chloride (CaCl₂), chlorine gas forms at the anode, and hydrogen gas is generated at the cathode as well. In the case of lead oxide (PbO), lead metal is deposited at the cathode, while oxygen gas is evolved at the anode.
