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 predominates. At High Temperature the blue color is strong. If we represent the equilibrium as: CoCl42 (aq) Co2+ (aq) + 4Cl (aq) We can conclude that: 1. This reaction is: A. Exothermic B. Endothermic C. Neutral D. More information is needed to answer this question. When the temperature is decreased the equilibrium constant, K: A. Increases B.
