Which of the following metal cations is the strongest oxidizing agent?
a) cu2+; eocu2+/cu = + 0.34 v
b) al3+; eoal3+/al = -1.66 v
c) sn2+; eosn2+/sn = -0.14 v
d) ag+; eoag+/ag = + 0.80 v
e) mn2+; eomn2+/mn = -1.18 v

Option (d) is the correct answer.

Explanation:

An oxidizing agent is defined as the substance that itself gains an electron and helps in oxidation of another substance.

For example,

Here, is the oxidizing agent.

Also, a substance with more positive value of electrode potential will be the strongest oxidizing agent. Whereas a substance with more negative value of electrode potential will be the strongest reducing agent.

Therefore, out of the given options has the highest positive value of electrode potential so, is the strongest oxidizing agent.

the atomic mass is the bottom number on the element.
