# Is NH_4OH + HCl an acid base reaction?

May 13, 2016

It is indeed an acid base reaction; but the base is NEUTRAL ammonia, not ammonium hydroxide.

#### Explanation:

${H}_{4} N O H$ is commercially available as ammonium hydroxide. A better representation would be as concentrated aqueous ammonia, i.e. $N {H}_{3} \left(a q\right)$ or $N {H}_{3} \cdot O {H}_{2}$; this latter representation has the same formula as $N {H}_{4} O H$.

So the rxn:

$H C l \left(a q\right) + N {H}_{3} \left(a q\right) \rightarrow N {H}_{4}^{+} + C {l}^{-}$

Thus $N {H}_{4} O H \equiv N {H}_{3} \cdot O {H}_{2}$, hydrated ammonia.
