Question

Oxidation reduction reaction

4. Substances A, B, C can all act as oxidizing agents. In solution, A is green, B is red, and C is yellow. I C ions, al ions, the color remains red. n the reactions in which they participate, they are reduced to A, B, and Il of which are colorless. When solution B is mixed with one containing C Which species is oxidized? Which species is reduced? When a solution of B is mixed with a from red to green. solution containing A ions, the color changes Which species is oxidized? Which species is reduced? Is B a better oxidizing agent than C? Is B a better oxidizing agent than A? Arrange A, B, and C in order of increasing strengths as oxidizing agents

Answer 1

Since the color doesn't change, hence no reaction occurs. This means that B cannot oxidize C- or C is a stronger oxidizing agent.

None is oxidized, none is reduced.

When B is mixed with A- then solution color changes from red to green which is color of A. That is B oxidises A, hence B is a stronger oxidizing agent than B.

A is oxidized, B- is reduced.

Is B a better oxidizing agent than C ? NO

Is B a better oxidizing agent than A ? YES

(Weakest oxidizing agent) A< B< C (strongest oxiding agent)
