Question

The pH of aqueous ammonium chloride is:

• A. Equal To $7$
• B. Less than $7$
• C. Greater than $7$
• D. Greater than or equal to $7$

Answer 1

The correct option is B

Less than $7$

The explanation for the correct option

(B) Less than $7$

the pH of aqueous ammonium chloride

• The formula of ammonium chloride is ${\mathrm{NH}}_4\mathrm{Cl}$.
• Ammonium chloride is a salt of strong acid $\left(\mathrm{HCl}\right)$and a weak base that is ammonia$\left({\mathrm{NH}}_3\right)$.
• These types of salts are acidic in nature.
• Hence, the pH of aqueous ammonium chloride is less than $7$.

The explanation for incorrect option

The pH of aqueous ammonium chloride is less than $7$. Hence, options (A), (C), and (D) are incorrect.

Hence, option (B) is correct. The pH of aqueous ammonium chloride is less than $7$.
