In aqueous solution cobalt(II) ion is surrounded by 4 water molecules and has a light pink color. When high concentrations of chloride ion ar-
a cobalt-chloride complex ion forms that has a distinctive blue color.
One way to represent this equilibrium is:
CoCl42 (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 CoCl42 (ad
