Cobalt chloride equilibrium. Experiment demonstrating the changes in equilibrium in cobalt chloride solutions that are heated (left) or cooled (right). At room temperature the cobalt and chloride ions are in equilibrium and the solution is a light pink colour. Heating the solution shifts the equilibrium and the solution turns blue. Cooling the solution shifts the solution in the opposite direction,intensifying the pink colour. This equilibrium is sensitive to concentration of solutes as well as temperature | |
