Oxidation is the loss of electrons. Which is losing electrons.
A. Pb is +4 on the left and +2 on the right. That's a gain of electrons so A can't be right.
B. O doesn't change oxidations state. B can't right.
C. H doesn't change oxidation state so C can't be right.
D. Cl changes from -1 on the left to zero on the right which is a loss of electrons. D must be the correct answer.
The element oxidized in the reaction described in PbO2 + 4HCl → 2H2O + PbCl2 + Cl2 is
A. Pb.
