In an aqueous chloride solution cobalt(II) exists in equilibrium with the complex ion CoCI42". Co2+(aq) is pink and CoCl42-(aq) is blue. At Low Temperature the pink color predominates. At High Temperature the blue color is strong. If we represent the equilibrium as: CoClą2-(aq)= Co2+(aq) + 4CI"(aq) We can conclude that: 1. This reaction is: A. Exothermic B. Endothermic C. Neutral D. More information is needed to answer this question. 2. When the temperature is increased the equilibrium constant, K:
