Question 1 Report

Sodium metal is always kept under oil because it
Answer Details
Sodium metal is always kept under oil because it reacts vigorously on exposure to air. Sodium is a highly reactive metal that reacts with moisture in the air, forming sodium hydroxide and releasing hydrogen gas. The reaction can be so vigorous that it can ignite the hydrogen gas produced, which can cause an explosion. To prevent this, sodium metal is kept under oil, which prevents contact with air and moisture.
