- Each pair of ions below is found together in aqueous solution. Using the table of solubility product constants in Appendix J, devise a way to separate these ions by adding a reagent to precipitate one of the ions as an insoluble salt and leave the other in solution.

- In Questions 1 through 6, you will be calculating the initial concentrations of Fe³+ ([Fe³+10) and SCN ([SCN]o) for each of the reactions you will perform. You should transfer the answers to these questions to the appropriate ICE table(s) on the "Data and Calculations" sheet. In all five reactions, you will be using 5.0 mL of 0.0020 M Fe(NO3)3. Each reaction mixture will be diluted to a final volume of 10.0 mL. What is [Fe³+]o in all five of the reactions you will study? Type your answer, WITHOUT UNITS, in the box below. Include 2 significant figures. If you want to enter your answers in scientific notation, use the format that Blackboard recognizes: 1.5 x 10-3 would be entered as 1.5E-3 (no spaces).
