WebThe pKa, also known as the acid dissociation constant, is an intrinsic property of such ionisable compounds and indicates the pH at which a functional group exists in solution as a 50:50 ratio of neutral : ionised species. If the pKa of a molecule is known, the degree of … WebVideo transcript. - [Instructor] Changing the pH of a solution can affect the solubility of a slightly soluble salt. For example, if we took some solid lead two fluoride, which is a white solid, and we put it in some distilled water, the solid is going to reach an equilibrium with the ions in solution.
