Question

Give reason:-
Aqueous solution of ammonia gives a pungent smell.

Answer 1

Aqueous solution of ammonia:

• Aqueous solution of ammonia is called ammonium hydroxide, ${\mathrm{NH}}_4\mathrm{OH}$.
• It is a weak base as it dissociates partially to give hydroxyl ions.
• Aqueous solution of ammonia gives a pungent smell because it is formed by bacterial breakdown of urea (${\mathrm{NH}}_2{\mathrm{CONH}}_2$) found in urine, ammonia aqueous solution has a pungent odor.
