Question

With restpect to $N{H}_3$, Ammonium ion is

• A. A conjugate acid
• B. A conjugate base
• C. Neither an acid nor a base
• D. Both acid and base

Answer 1

The correct option is A A conjugate acid

The formula of ammonium ion is $N{H}_4^{+}$. It is the conjugate acid of base $N{H}_3$.
The reaction is $\begin{array}{cc}N{H}_3+H^{+}\to & N{H}_4^{+}\\ base& Conjugateacid\end{array}$
