Question

Sodium is always kept in kerosene. Write scientific reason

Answer 1

Sodium is the highly reactive alkali metal. It reacts vigorously with oxygen gas and catches fire.

The water and air contains oxygen and hence the metal reacts with water and moisture in the air.

Therefore, in order to cut off its contact with air and water and prevent the accidental damage, sodium metal is kept in kerosene oil.

 Kerosene is a mixture of hydrocarbons and sodium does not react with it. 

Answer 2

heya answer is here.........

◇Sodium (Na) is a very reactive metal. It is kept in kerosene to prevent it from coming in contact with oxygen and moisture. If this happens, it will react with the moisture present in air and form sodium hydroxide. This is a strongly exothermic reaction, and lot of heat is generated.
