You're provided with a purple-colored solution of CoCl2.6H2O in aqueous HCl. You determine that [Cl-]tot initially in solution is equal to 3.105 M. You heat a small volume of the solution in a hot water bath to 50 C. If [CoCl42-] = 0.046 M at 50 C at equilibrium, what must be the equilibrium value of [Cl-] at 50 C?
