Substances A2, B2, and C2 can act as oxidizing agents. Solution A2 is green, B2 is yellow, and C2 is red. In the reactions in which they participated they are reduced to A-, B-, and C- ion, all of which are colorless. When a solution of A2 is mixed with one containing B- ions, the color is changed from green to yellow.
Which species is oxidized?
Which species is reduced?
When a solution of A2 is mied with one containing C- ions, the color remains green.
Is A2 a better oxidizing agent than C2?
Is A2 a better oxidizing agent than B2?
Arrange A2, B2, C2 in order of increasing strengths as oxidizing agents.
