Sodium metal is stored in-

Correct option is A

The correct answer is (a) Kerosene.
· Sodium metal is highly reactive, especially with water and air. To prevent it from reacting with moisture and oxygen in the air, it is stored in kerosene. Kerosene acts as a protective layer, keeping the sodium stable and preventing dangerous reactions like explosions or the release of hydrogen gas.
Information Booster:
Ether:
· An organic solvent, but not suitable for storing sodium as it does not provide the necessary protection from moisture and air.
Water:
· Sodium reacts violently with water, producing hydrogen gas and heat, which can lead to an explosion.
Acetone:
· A solvent used for cleaning and dissolving substances, but not safe for storing sodium as it may not prevent reactions with air.
