Question
---This was the previous one---
Substances A, B, and C can all act as oxidizing agents. In solution, A is green, B is yellow, and C is red. In the reactions in which they participate, they are reduced to A-, B-, and C- ions, all of which are colorless. When a solution of C is mixed with one containing B- ions, the color changes from red to yellow.
Which species is oxidized? Which is reduced?
When a solution of C is mixed with one containing A- ions, the color remains red.
Is C a better oxidizing agent than A?
Is C a better oxidizing agent than B?
Arrange A B and C in order of increasing strength as an oxidizing agent.
C + B^- ==> C^- + B
You know B^- us colorless and it turns yellow which is the color of B. So the reaction is as I wrote above.
C gains electrons in going to C^- so it is reduced. B^- loses electrons in going to B. It is oxidized.
C+ A^- ==> stays red which means no reaction.
So we have these reactions.
C + A^- ==> N.R.
C + B^- ==> C^- + B
What is an oxidizing agent? That is the gain of electrons is the substance reduced which makes it the oxidizing agent. So C ==> C^- is the gain of electrons which means those reactions above shows which is the stronger oxidizing agent.
C reacts with B^- which means C is a better oxidizing agent than B.
C does not react with A^- which means that A is a stronger oxidizing agent than C.

You are given an unknown, colorless, solution that contains one of the following salts: NaA, NaB, NaC. In solution, each salt dissociates completely into the Na+ ion and the anion A-,B-,C-. The Na+ ion is effectively inert. Develop a simple procedure for identifying the salt that is present.

Is this part of the same question? If so you must have some of A, some of B and some of C
Mix A with the three. It will not react with A^- but will with B^- and C^-
Mix B with the three. It will not react with A or B or C.
Mix C with the three and it will not react with A but will with B.
Then make the choices.
This follows the strength as an oxidizing agent of A, C, B.
