Question

$N{H}_{4}OH$ is a weak base because:

• A. it is completely ionised
• B. it has low vapour pressure
• C. it has low density
• D. it is only partially ionised

Answer 1

The correct option is D it is only partially ionised

Solution:- (D) it is only partially ionised

$N{H}_{4}OH$ is a weak base because it partially ionised in water and produce a small amount of hydroxide ions $\left({OH}^{-}\right)$.

$N{H}_{4}OH\rightleftharpoons {N{H}_4}^{+}+{OH}^{-}$
