# Why does sodium metal have different properties than does sodium chloride?

Oct 16, 2016

Because sodium chloride is not sodium metal.

#### Explanation:

You have two different materials: an alkali metal; and an alkali metal salt.

Their reaction with water is expected to be different, and indeed is different:

Na(s) + H_2O(l) rarr Na^(+)(aq) + ""^(-)OH(aq) + 1/2H_2(g)uarr

$N a C l \left(s\right) \rightarrow N {a}^{+} \left(a q\right) + C {l}^{-} \left(a q\right)$
