Assume we have a solution that contains 0.050 mol/L of Ba2+ and 0.050 mol/L Mg2+. Calculate the concentration of Ba2+ left in solution at the point that Mg2+ just begins to precipitate. Assume the solution volume (and thus the ion concentration) do not change as we add carbonate ion. The Ksp of barium carbonate is given in table 1 of the experiment 212 handout (8.1x10^-9). The Ksp of magnesium carbonate is 4.0x10-5. write balanced chemical equations and Ksp expressions for each of the salts as part of your solution
