How can 6m nitric acid be used to identify co2 3 ions dissolved in the same solution with so2 4 and po3 4 ions? 2. How can you distinguish between so2 4 and po3 4 if they are present in the same solution? 3. What would you do and how would you know that a precipitate contained either agcl, or agi, or both? 4. Why should you test for the presence of no 3 ions in a solution before testing for the presence of cl and i ions in that solution? 5. Why should a person not test for the presence of no 3 ions in a solution that he or she plans to subsequently test for the presence of sulfate ions, so2 4 ?

Answer the questions about this reaction: nai(aq) + cl2(g) → nacl(aq) + i2(g) write the oxidation and reduction half-reactions: oxidation half-reaction: reduction half-reaction: based on the table of relative strengths of oxidizing and reducing agents (b-18), would these reactants form these products? write the balanced equation: answer options: a. 0/na -> +1/na+1e- b. nai(aq) + cl2(g) → nacl(aq) + i2(g) c. +1/na+1e- -> 0 /na d. -1/2i -> 0/i2+2e- e. no f. 4nai(aq) + cl2(g) → 4nacl(aq) + i2(g) g. 2nai(aq) + cl2(g) → 2nacl(aq) + i2(g) h. 4nai(aq) + 2cl2(g) → 4nacl(aq) + 2i2(g) i. nai(aq) + cl2(g) → nacl(aq) + i2(g) j. 0/cl2+2e -> -1/2cl- k. yes
