answer question 2, a-e

Pre-Laboratory Exercise: 1. On a separate sheet of paper, draw the flow diagram for the separation and identification of the ions in group II. Do not turn the diagram in with the Pre-Lab: you will need it for lab. 2. Write balanced net ionic equations for the following reactions. a. The precipitation of the Snion in step 1. (2 pts) SnCI" +4HCO Sn02 +420 2 + 2H20 +6C1- b. The dissolving of Crin step 2. (2 pts) c. The reduction of Sn" to Snin step 4. (2 pts) d. The dissolving of iron Ill hydroxide in hot HCl in step 6. (2 pts) e. The confirmatory test for Zro in step 8. (2 pts) (16 pts) 3. A solution containing one or more of the six Group Il ions was treated with ammonia at a pH of 9-10. The newly formed hydroxide precipitate is insoluble in NaOH and HO, The remaining hydroxide precipitate from the first step is treated with H.O, and HCI. Part of the solution was added to distilled water and a white precipitate formed. State which ions are present, absent, or in doubt (i.e. more testing/observations would be needed). Confirmatory tests are not always necessary to make a determination present absent in doubt State your reasoning: Appendix-s Pre-Laboratory Exercise: 1.
