hydrolysis of salts

Question

An aqueous solution of NH₄Cl is:

RankGuru · Accepted Answer

**Ammonium chloride ($NH_4Cl$)** is a salt formed from a **Weak Base ($NH_3$)** and a **Strong Acid ($HCl$)**.
- In water, it dissociates: $NH_4Cl 	o NH_4^+ + Cl^-$.
- The $Cl^-$ ion is the spectator ion (from strong acid).
- The $NH_4^+$ ion (conjugate acid of weak base) reacts with water (**Cationic Hydrolysis**):
$NH_4^+ + H_2O ightleftharpoons NH_{4}OH + H^+$
- The liberation of $H^+$ ions makes the solution **acidic** ($pH < 7$).
