**Oxidizing Agents and Anion Identification**
**2. Analysis of Oxidizing Agents**
Substances A, B, and C can all act as oxidizing agents. In solution, these substances display distinct colors: A is green, B is yellow, and C is red. The anions for these solutions are colorless. When solutions are mixed, color changes indicate reactions:
- Mixing A with B changes the color from green to yellow.
- Mixing A with C results in no color change; the solution remains green.
**Task: Arrange A, B, and C in order of oxidizing strength and explain your answer.**
*Observations and Explanation*:
- Mixing A (green) with B (yellow) results in a yellow color, suggesting that A is oxidized by B.
- Mixing A with C and observing no color change implies no reaction— there is no oxidation occurring.
Conclusion: The order of oxidizing strength is C > A > B, as C does not get oxidized by B, indicating its superior oxidizing ability.
Additional Notes:
- **Oxidizing agents** are substances that accept electrons from other substances.
**3. Identification of Anion in Unknown Salt Solution**
Given an unknown salt solution, which may contain NaA, NaB, or NaC (all soluble), develop a procedure to identify the anion using data from question 2.
- **Unknown NaA, NaB, NaC = all are soluble.**
From the observations:
- **C** is identified as the best oxidizing agent.
- **A** is a moderate oxidizing agent.
- **B** is the least oxidizing agent.
Use this knowledge to test the unknown solution by attempting reactions similar to those described, observing color changes to identify the anion present.
