Question
Show transcribed image text 2. The ions A^-, B^-, and C^- all form colorless aqueous solutions. Their molecular counterparts, however, form brilliantly colored solutions, where A2 is green, B2 is blue, and C2 is red. When a student mixes the anions C- and A with a solution of 82, the following results were obtained: i) B + 2 C^- right arrow red solution (B2 oxidized C^- to C2) ii) B2 + 2 A^- right arrow blue solution (B2 does not oxidize A^- to A2) a) Rank A2, B2, and C2 in order of increasing oxidizing strength. b) Would the following reaction occur? A2 + 2 C^- right arrow C2 + 2 A^- Explain why or why not. c) Devise a single-step test that one could use to analyze an unknown solution containing one of the three anions: A^-, B^-, or C using either A2, B2 or C2 as a test solution. Explain how and why this would work.
