Question

Write the equation of the reaction. Which species is oxidized? Which species is reduced?
Is A or B the better oxidizing agent? Is A or C the better oxidizing agent?
Arrange A, B, and C in order of increasing strengths asoxidizing agents.

Explanation / Answer

When A is mixed with C- A + C- => A- + C C- is oxidized to C A is reduced to A-; (A is a better oxidizing agent than C, becauseit causes C- to be oxidized) When A is mixed with B-, no reaction occurs. That means A- and Bcannot be formed. This means if B is mixed with A-, B- and A willform, so B is a better oxidizing agent than A Summary: B is better than A; A is better than C Strength as oxidizing agent: C
