When sodium metal is added to ethanol, the following chemical reaction takes place:
`2 C_2H_5OH + 2Na -> 2C_2H_5ONa + H_2`
Thus, we can see that hydrogen gas is evolved when sodium reacts with ethanol. Along with the gas, sodium ethoxide is also generated. When we evaporate the solution, we end with a precipitate of sodium ethoxide.
A similar reaction of sodium also takes place with waterand we obtain the same gas. This chemical...

A similar reaction of sodium also takes place with water and we obtain the same gas. This chemical reaction can be written as:
`2Na + 2H_2O -> 2NaOH + H_2`
Here, sodium hydroxide and hydrogen gas are the products and hence the reaction is similar to that between sodium and ethanol.
Incidentally, a reaction of sodium with other alcohols (such as methanol, propanol, etc.) will also be along the similar lines and will generate hydrogen gas.
Hope this helps.
