Why is sodium stored under oil?

ChemistryLaboratory safety

Quick Answer

Sodium is stored under oil to keep it away from air and moisture, which would make it react quickly. The oil barrier prevents dangerous oxidation and contact with water vapor.

The Full Story

Sodium metal is highly reactive, especially with water and oxygen in the air. If left exposed, it can quickly tarnish and may even react enough to become unsafe to handle. Storing it under mineral oil or another inert liquid blocks moisture and oxygen from reaching the metal surface. This simple precaution is common in laboratories and helps prevent fires or violent reactions.

Key Facts

1.Sodium is highly reactive with air and water
2.Mineral oil is used as a protective barrier
3.The storage method helps prevent fires and corrosion
