By comparing standard reduction potentials, we can compare the reduction and oxidation powers of elements or ionic species. Some standard reduction potential values are given in Table 1.


Which of the following will act as an oxidizing agent the most?

A Na+
B Ag+
C Cl2
D Pb2+
Ans. C The question asks for the best oxidizing agent. An oxidizing agent gets reduced in the process. So the oxidizing agent (species) should be able to accept electrons with ease. The most positive reduction potential is that of chlorine (Cl2), which makes chlorine the best oxidizing agent among the choices.
