# What is "sodium ethoxide"?

Sodium ethoxide is the sodium salt of ethanol, ${H}_{3} C - C {H}_{2} O H$
${H}_{3} C - C {H}_{2} O H + N a \rightarrow {H}_{3} C - C {H}_{2} {O}^{-} N {a}^{+} + \frac{1}{2} {H}_{2} \uparrow$
The $C - H$ and $C - C$ bonds, and the $C - O$ and $O - H$ bonds are all covalent bonds; there is a formal negative charge on the oxygen atom, and a formal positive charge on the sodium atom: a formal ionic bond. Sodium ethoxide could be isolated as a solid.
