in which of the following dissociation of NH₄OH will be minimum?

Solution

NH₄OH is a weak base. Dissociation of NH₄OH will be minimum in NH₄Cl because of common ion effect.The common ion (NH₄⁺) present in solution suppresses the ionization of NH₄OH by adding more of an ion which is a product of this equilibrium.
