# Is sodium reactive?

Oct 30, 2016

What do you think?

#### Explanation:

Sodium is usually stored under thick mineral oil.

When you cut a clean surface of metal and expose it to the air it tarnishes rapidly.

With water, the reaction with sodium is rapid and vigorous:

$N a \left(s\right) + {H}_{2} O \left(l\right) \rightarrow N a O H \left(a q\right) + \frac{1}{2} {H}_{2} \left(g\right) \uparrow$

All of this denotes considerable reactivity.
