Sodium metal is kept under:

  • A.Petrol
  • B.Alcohol
  • C.Water
  • D.Kerosene

Answer: D

Sodium is stored under kerosene. It reacts violently with water and even with the moisture in air, so it must be kept away from both.

Kerosene works because it is a hydrocarbon that does not react with sodium and is dense enough to keep the metal covered. Sodium in air quickly forms an oxide crust and can catch fire.
