Will the pH of an aqueous solution of `NH_4Cl` greater, equal or less than 7 ?

Explanation

To determine whether the pH of an aqueous solution of \( NH_4Cl \) is greater than, equal to, or less than 7, we can follow these steps:

### Step 1: Identify the nature of \( NH_4Cl \)
\( NH_4Cl \) is a salt formed from the weak base \( NH_4OH \) (ammonium hydroxide) and the strong acid \( HCl \) (hydrochloric acid).

### Step 2: Understand the hydrolysis of the salt
When \( NH_4Cl \) is dissolved in water, it dissociates into \( NH_4^+ \) ions and \( Cl^- \) ions. The \( Cl^- \) ion does not undergo hydrolysis as it is the conjugate base of a strong acid. However, the \( NH_4^+ \) ion, being the conjugate acid of a weak base, will undergo hydrolysis.
