Question

what is common ion effect?

plz tell me

Answer 1

The common-ion effect states that in a chemical solution in which several species reversibly associate with each other by an equilibrium process, increasing the concentration of any one of its dissociated components by adding another chemical that also contains it will cause an increased amount of association.

Answer 2

Hello !!!

Common Ion Effect is defined as the suppression in ionization of weak electrolyte by addition of another electrolyte which contain a common ion.

e.g CH3COOH <=> CH3COO- + H+

which contains acetate ions. When we add CH3COONa which also contain CH3COO-, the ionization of Acetic Acid get suppressed .


Thank You !!!!
