Hydrolysis of the salt:
When Ammonium Chloride is dissolved in water, it dissociates into Ammonium ions (NH4+) and Chloride ions (Cl-). Ammonium hydroxide is a weak base that partially dissociates in water to form Ammonium ions (NH4+) and Hydroxide ions (OH-). The presence of Ammonium Chloride provides additional Ammonium ions, which can combine with Hydroxide ions resulting from the dissociation of Ammonium hydroxide. This reaction results in the formation of more Ammonium hydroxide, which leads to an increased degree of dissociation of Ammonium hydroxide.
Common Ion effect:
The presence of a common ion, in this case, Ammonium ions (NH4+), suppresses the ionization of Ammonium hydroxide. However, in the case of Ammonium hydroxide and Ammonium Chloride, the common ion (Ammonium ion) actually increases the dissociation of Ammonium hydroxide. This is because the common ion (Ammonium ion) combines with the Hydroxide ions produced during the dissociation of Ammonium hydroxide, shifting the equilibrium towards the dissociation of Ammonium hydroxide.
Therefore, the increase in the degree of dissociation of Ammonium hydroxide in the presence of Ammonium Chloride is primarily due to the hydrolysis of the salt, where the common ion effect plays a crucial role in enhancing the dissociation process.

Explanation: Common Ion effect is defined as the separation of the dissociation of a weak electrolyte by the addition of a strong electrolyte having some common ion. Therefore the degree of dissociation of Ammonium hydroxide decreases in the presence of Ammonium Chloride due to common Ion effect.
