Q.18 A: Sodium is stored in kerosene.R: Sodium is very reactive and may cause fire when in contact with air or water ​

Sodium and Potassium are highly reactive metals and react vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn't react with kerosene.
