Solution: Three cations, Ni2+, Cu2+, and Ag+, are separated using two different precipitating agentsBased on Figure 17.22 in the textbook, what two precipitating agents could be used?

Problem

Three cations, Ni2+, Cu2+, and Ag+, are separated using two different precipitating agents1. Mixture of cations A, B, and C in test tube. 2. Add first precipitating agent.  Cation A is removed as precipitate, B and C remain in solution 3. Decant liquid.  Only cations B and C remain. 4. Add second precipitating agent.  Cation B is removed as precipitate, cation C remains in solution. 5. Decant liquid.  Only cation C remains.

Based on Figure 17.22 in the textbook, what two precipitating agents could be used?
