Question

Name a metal which is kept immersed in kerosene oil. Why is it kept this way?

Answer 1

Sodium metal is kept immersed in kerosene oil.
Sodium is a very active metal that combines with oxygen at room temperature and burns with a brilliant golden-yellow flame. It reacts violently with water to produce hydrogen gas, which may be ignited by the heat of the reaction. So, it is kept in kerosene oil.
