Write balanced chemical equations and ksp expressions for, Ask an Expert

Academics

Assume we have a solution that contains 0.050 mol/L of Ba^2+ and 0.050 mol/L Mg^2+. Calculate the concentration of Ba+ left in solution at the point that Mg+ just begins to precipitate. Assume the solution volume (and thus the ion concentrations) do not change as we add carbonate ion. The Ksp for Barium is 8.1 X 10^ -9 and the Ksp for Magnesium carbonate is 4.0 X 10^ -5. Write balanced chemical equations and Ksp expressions for each of the salts as part of your solution.
