Sodium reacts with Ethanol
Explanation:
When sodium metal is dropped in a test tube containing ethanol, sodium ethoxide is formed with the evolution of hydrogen gas. This is a characteristic reaction of alcohols, where the alcohol reacts with sodium metal to form the corresponding alkoxide and hydrogen gas. Hydrogen gas evolves with a pop sound.
The chemical equation of this reaction is:
2C2H5OH + 2Na ------> 2C2H5ONa + H2
