The questions below refer to the following system:
| Co(H 2O) 62+ + 4 Cl - CoCl 42- + 6H 2O |
When cobalt(II) chloride is added to pure water, the Co2+ ions hydrate. The hydrated form then reacts with the Cl- ions to set up the equilibrium shown here.
Which statement below describes the change that the system will undergo if silver nitrate is added?
Reference: Ref 13-8
