Interpretation:
The visual change when the given reaction mixture is placed in an ice bath needs to be explained.
Concept introduction:
Le Chatelier principle states that a system at equilibrium when subjected to changes in the system adjusts it self to attain the equilibrium state again.
Answer to Problem 58A
When placed in an ice bath the reaction mixture will turn deep blue in colour due to the reaction being endothermic. On cooling, reverse reaction will become more favorable and amount of Co(H2O)6 will increase.
Explanation of Solution
Since the reaction is endothermic placing the mixture in an ice bath will reduce its temperature and according to Le Chatelier’s principle the equilibrium will shift to the left which will increase the amount of reactants and make the solution blue.
The solution will turn blue in an ice bath due to the higher concentration of reactants.
