# Does sodium chloride undergo chemical reaction with water?

Oct 2, 2015

Yep. While sodium chloride does not hydrolyze water, it does undergo ionization.

#### Explanation:

When NaCl is dissolved in water, ionization occurs to form aquated $N {a}^{+}$, and $C {l}^{-}$ ions.

We could represent the reaction as follows:

$N a C l \left(s\right) \stackrel{{H}_{2} O}{\rightarrow} N {a}^{+} \left(a q\right) + C {l}^{-} \left(a q\right)$.

$N {a}^{+} \left(a q\right)$ represents the aquated sodium ion, which we could formulate as ${\left[N a {\left(O {H}_{2}\right)}_{6}\right]}^{+}$, that is 1 sodium ion surrounded by, or aquated by 6 water molecules. No acid/base chemistry occurs.
