Heating Cooling Systems

The formation of CoCl4 2 – Co 2 + and Cl-is endothermic. Are the color changes accompanying the heating and cooling equilibrium mixture according to Le Chatelier's principle? Please explain. Thank you. Well, I have the answer. Heat and [pinkCo (H2O) 6] 2 and 4 Cl -> [Blueco (Cl) 4] -2, 6 H2O by Le Chatelier's principle, adding more than any of the three to the left. . I.e. Hotter or Cl-, will be conducting the reaction to the right side, the blue side by Le Chatelier's principle, the removal of any of the three at the left side. . Fresh IE or eliminate Cl-withthe addition of Ag +, will drive the reaction to the left side, the side pink
