If you have ever seen the littler "weather change" houses, then you would see the instructions say that the figure appears blue when dry weather is expected and pink when a storm is appraoching, i.e., wet weather. The equilibrium reaction is: Blue color [CoCl4]-(aq) + 6H2O(g or l) <---> pink color [Co(H2O)6]2+(aq) + 4Cl-(aq) As the storm leaves the area, the water dries up and the equilibrium shifts left. a. What would happen if you exposed the system to table salt? b. What would happen if you moved the system to the bathroom and turned on the shower? c. If you place the little house in the oven on low, it either stays blue or else it turns from pink to blue. Is the reaction as written exothermic or endothermic? Explain

Question
If you have ever seen the littler "weather change" houses, then you would see the instructions say that the figure appears blue when dry weather is expected and pink when a storm is appraoching, i.e., wet weather. The equilibrium reaction is:
Blue color [CoCl4]-(aq) + 6H2O(g or l) <---> pink color [Co(H2O)6]2+(aq) + 4Cl-(aq)
As the storm leaves the area, the water dries up and the equilibrium shifts left.
a. What would happen if you exposed the system to table salt?
b. What would happen if you moved the system to the bathroom and turned on the shower?
c. If you place the little house in the oven on low, it either stays blue or else it turns from pink to blue. Is the reaction as written exothermic or endothermic? Explain.
