Question

The conjugate acid of $N{H}_2^{-}$ is

• A. $N{H}_3$
• B. $N{H}_4^{+}$
• C. $N_2{H}_4$
• D. $N{H}_{2}OH$

Answer 1

The correct option is A $N{H}_3$

A conjugate acid is a species formed by gain of proton by the base.
$N{H}_2^{-}\left(aq\right)+H^{+}\left(aq\right)\rightleftharpoons N{H}_3\left(aq\right)BaseConjugateAcid$
