I DO NOT understand the following! Please HELP :)

1st Part
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 A- ions, the color changes from red to green.
1) Which species is oxidized?
2) Which is reduced?

2nd Part
When a solution of C is mixed with one containing B- ions, the color remains red.
1) Is C a better oxidzing agent than A?
2) Is C a better oxidizing agent than B?

Part 3
Arrange A, B, and C in order of increasing strengths as oxidizing agegnts.

I responded to your earlier post.

1st Part:

To determine which species is oxidized and which is reduced, you need to understand the concept of oxidation and reduction.

Oxidation is a chemical process where a substance loses electrons, while reduction is a process where a substance gains electrons. In this case, A, B, and C are all oxidizing agents, which means they accept electrons from other substances.

In the given reactions, A, B, and C are reduced to A-, B-, and C- ions, which are colorless. When C is mixed with a solution containing A- ions, the color changes from red to green.

To identify which species is oxidized and which is reduced, you need to look at the change in color. The substance that causes the change in color is being reduced, and the substance that stays the same in color is being oxidized.

So, in this case:
1) Species C is reduced since it changes color from red to green.
2) Species A- is oxidized since it doesn't change color.

2nd Part:
To determine if C is a better oxidizing agent than A and B, you need to analyze their reactions.

When C is mixed with a solution containing B- ions, the color remains red. This indicates that no reaction occurs. If a reaction had occurred, there would have been a change in color.

1) Since the reaction between C and A- resulted in a color change, it suggests that C is a stronger oxidizing agent than A.
2) Since no reaction occurred between C and B-, it suggests that C and B have similar oxidizing strengths.

Part 3:
To arrange A, B, and C in order of increasing strengths as oxidizing agents, you can use the information obtained from the previous parts.

Based on the information provided, the order of increasing strengths as oxidizing agents is:
B < C < A

This is because the reaction between C and A- resulted in a color change, indicating that C is a stronger oxidizing agent than A. No reaction occurred between B- and C, suggesting that B has the lowest oxidizing strength among the three substances.
