Calculating the value requires knowing those concentrations, the balanced equation for the solution and plugging in those values to the equation Ksp = [C]^c * [B]^b. Solubility is the ability of a substance to dissolve. Therefore, the equilibrium concentrations of each ion are equal to . Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Lead sulfates and carbonates are very insoluble, so will precipitate out of solution very easily. The Ksp expressions in terms of  s can be used to solve problems in which the Ksp is used to calculate the molar solubility as in the examples above. For example, if your substance dissolved in 500 mL of water, 0.0021 moles per liter × 0.5 liters = 0.00105 moles. Use the molar mass to convert from molar solubility to solubility.

Chemistry books and websites have tables of ionic solids and their corresponding solubility product constants. To find the concentration, substitute X for each ion, as follows: This treats each ion as distinct, both of which have a concentration molarity, and the product of those molarities equals Ksp, the solubility product constant. Use the molar mass to convert from molar solubility to solubility. In this case the setup of the ICE table would look like the following: When the Ksp expression is written in terms of , we get the following result for the molar solubility. On the right side, you break out each ion in square brackets. You have to make sure to specify the temperature because, obviously, if you change the temperature, you change how much can dissolve in the water. Let's take a look at this exercise.
