Also, here's an old quiz question:

An aqueous solution which contains the barium cation (Ba)2+ is mixed with a second aqueous solution that contains that chromate ion ( CrO4)2- and a yellow precipitate forms that is barium chromate, BaCrO4 (s). The equilibrium constant for this reaction is: Kc = 4.17 x 109.
(a) Write the equation for the reaction as an equilibrium.

(b) Write the equilibrium expression for the reaction.

If the initial concentrations of (Ba)2+ and (CrO4)2- are each 0.0500 M immediately after mixing the two solutions, what is the final concentration of all species ?
