What will be the pH of aqueous solution of NH₄ Cl ?

NH₄ Cl is a salt produced by the neutralization reaction between a strong acid (HCl) and a weak base (NH₄OH). The reaction between them can be represented as follows:

HCL + NH₄OH → NH₄CL + H₂O

Hydrolyses of NH₄CL tales place as follows:

NH₄ ⁺ + H₂O → NH₃ + H₃O ⁺

Its produces H₃O ⁺ and that’s why the aqueous solutions of salt produced by neutralization of strong acid and a weak base are acidic in nature. Therefore, pH < 7.
