8.11 pH and Solubility

Identify the qualitative effect of changes in pH on the solubility of a salt.

• The solubility of a salt is pH sensitive when one of the constituent ions is a weak acid, a weak base, or the hydroxide ion. These effects can be understood qualitatively using Le Châtelier’s principle.
  • Exclusion: Computations of solubility as a function of pH will not be assessed on the AP Exam.
