In an aqueous chloride solution cobalt() exists in equilibrium with the complex ion CoCl2 Co²+ (aq) is pink and CoC1,² (aq) is blue.
At low temperature the pink color predominates. At high temperature the blue color is strong.
If we represent the equilibrium as:
Co² (aq) + 4C1 (aq) CoCl² (aq)
We can conclude that
1. This reaction is
O exothermic.
O endothermic.
