Question

4.a)What is common ion effect?
b)Calculate the solubility of A2X3; in pure water, assuming that neither kind of ion react
with water. The solubility product of A2X3 Ksp = 1.1 X 10-23​

Answer 1

Answer:

The common-ion effect refers to the decrease in solubility of an ionic precipitate by the addition to the solution of a soluble compound with an ion in common with the precipitate. This behaviour is a consequence of Le Chatelier's principle for the equilibrium reaction of the ionic association/dissociation
