Why is sodium stored in oil?
Quick Answer
Sodium is stored in oil because it reacts quickly with air and moisture. The oil keeps water and oxygen away from the metal.
The Full Story
Sodium metal is so reactive that it tarnishes quickly in air and can react violently with water. Storing it under mineral oil or another inert liquid prevents contact with moisture and oxygen, which would otherwise start oxidation and dangerous heat-producing reactions. This simple storage method is a standard safety practice in chemistry labs. Sodium’s reactivity is one reason it is found naturally only in compounds, not as free metal in nature.
