Besides salt, what is the other product of a neutralization reaction?

Neutralization reaction:

1. In a neutralization reaction, an acid is added to a base forming salt and water as product.
2. Salts are ionic compounds consisting of an anion from an acid and cation from a base.

$\mathrm{Acid}+\mathrm{Base}\to \mathrm{Salt}+\mathrm{Water}$

$$\begin{gathered} \mathrm{HCl}\left(\mathrm{aq}\right)+\mathrm{NaOH}\left(\mathrm{aq}\right)\to \mathrm{NaCl}\left(\mathrm{aq}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right) \\ (\mathrm{Hydrochloric}\mathrm{acid})(\mathrm{Sodium}\mathrm{hydroxide})(\mathrm{Sodium}\mathrm{chloride})\left(\mathrm{Water}\right) \end{gathered}$$

Therefore, besides salt, the other product formed in a neutralization reaction is Water (${\mathrm{H}}_2\mathrm{O}$).
