7.11 Introduction to Solubility Equilibria

Calculate the solubility of a salt based on the value of Ksp for the salt.

• The dissolution of a salt is a reversible process whose extent can be described by Ksp, the solubility-product constant.
• The solubility of a substance can be calculated from the Ksp for the dissolution process. This relationship can also be used to predict the relative solubility of different substances.
• The solubility rules (see
• The molar solubility of one or more species in a saturated solution can be used to calculate the Ksp of a substance.
