While we can calculate the solubility by measuring each substance and following an equation, the solubility rules allow us to determine the solubility of a substance before you attempt to create it. Suppose we have a solution that is 0.100 M in CI- and in. The extent of the solubility of a substance in a specific solvent is measured as the saturation concentration, where adding more solute does not increase the concentration of the solution and begins to precipitate the excess amount of solute. The solubility product expression is as follows: Ksp = [Ba2 +][SO2 4] = 1.08 10 10 B To solve this problem, we must first calculate the ion product: Q = [Ba2 +][SO2 4] using the concentrations of the ions that are present after the solutions are mixed and before any reaction occurs.
