The solubility product constant for Ba(IO3)2 is 1.57×10-9 at 25 oC. What is the molar concentration of IO3- ions in a saturated solution of Ba(IO3)2? Assume an ideal solution at 25 oC. How many grams of Ba(IO3)2 (487.1 g/mol) can be dissolved in 1000 mL of pure water at 25 oC? How many grams of Ba(IO3)2 can be dissolved in 1000 mL of a 0.100 M KIO3 solution at 25 oC? Use activities for this calculation.

Learning Goal: To understand the relationship between precipitation and the solubility product and to be able to predict whether a substance will precipitate or not. Precipitation is the formation of an insoluble substance. For the equation AB(s)⇌A+(aq)+B−(aq), precipitation represents a shift to the left and the production of a solid. From Le Châtelier's principle, we know that when the product of the concentrations of A+ and B− gets above a certain level, the reaction will respond by shifting left to...
