In an aqueous chloride solution cobalt(II) exists in equilibrium with the complex ion CoCl42-. Co2 (aq) is pink and CoCl42-(aq) is blue. At Low Temperature the pink color pre-dominates. At High Temperature the blue color is strong. If we represent the equilibrium as:
CoCl4^2-(aq) <--> Co2+(aq) + 4Cl-(aq)
We can conclude that:___.
