The questions below refer to the following system:
Co(H2O)6 2+ + 4Cl- ⇌ CoCl4 2- + 6 H2O
When cobalt(II) chloride is added to pure water, the CO2+ ions hydrate. The hydrated form then reacts with 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?
