Small math error on his part. Its solubility product is 1.08 1010 at 25C, so it is ideally suited for this purpose because of its low solubility when a barium milkshake is consumed by a patient. The Beer-Lambert law relates the absorption of light by a solution to the properties of the solution according to the following equation: A = bc, where is the molar absorptivity of the absorbing species, b is the path length, and c is the concentration of the absorbing species. For our problem, we're gonna calculate QSP, which has the same form as KSP, the differences the concentrations can be at any moment in time. What is the concentration of the chloride ion in a solution that is 0.300 M KCl and 0.200 M CaCl_2? For dilute solutions, the density of the solution is nearly the same as that of water, so dissolving the salt in 1.00 L of water gives essentially 1.00 L of solution.
