Question

Substances A, B, C can all act as oxidizing agents. A is green, B is red & C is yellow. In the reactions in which they participate, they are reduced to A-, B-, C- ions. All are colorless. When solution B is mixed with one which contains solution C-, the color changes to yellow. Which species is oxidized? Which is reduced? When a solution of C is mixed with one containing A- ions, the color goes from yellow to green. Which is oxidized and which is reduced? Is B better than C? Arrange A, B & C in order of increasing strengths as oxidizing reagents.

Explanation / Answer

1)

B + C- ----------------> C + B-

C- is oxidised

B is reduced

2)

C + A- ------------------> A + C-

A- is oxidised

C is reduced

oxidizing agent order : A > C > B

no B is not better oxidizing than C
