Question

Acidity of ammonium hydroxide is:

• A. 1
• B. 2
• C. 4
• D. 3

Answer 1

The correct option is A 1

The basicity of any base is the number of hydroxyl groups released by that base.

Ammonium hydroxide ($N{H}_{4}OH$) is a base and it dissociates as follows in the solution medium:-

$N{H}_{4}OH\leftrightharpoons N{H}_4^{+}+(OH{)}^{-1}$

Since it releases one hydroxyl group, it's basicity is one.

Hence, the correct answer is option (A).
