In aqueous solution cobalt(II) ion is surrounded by 4 water molecules and has a light pink color. When high concentrations of chloride ion are introduced, a cobalt-chloride complex ion forms that has a distinctive blue color. One way to represent this equilibrium is: Cocl,"(aq) = Co2+ (aq) + 4 CI" (aq) An experiment was run to demonstrate that a dynamic equilibrium exists between these two ions. Starting with a special form of CoC142(aq) where one of the chloride ions was...
