Sodium is stored in kerosene because it is a very highly reactive soft metal and can react with other substances easily..

Sodium Storage in Kerosene

Sodium, a highly reactive metal, is commonly stored in kerosene due to several factors that ensure its stability and prevent it from reacting with air or water. This method of storage is widely used in laboratories, industrial settings, and chemical research facilities where sodium is utilized. The rationale behind storing sodium in kerosene is explained below:

Prevention of Oxidation:
Sodium is a highly reactive metal that readily reacts with oxygen in the air, resulting in the formation of sodium oxide. This reaction is highly exothermic and can lead to the release of a significant amount of heat and sparks. By storing sodium in kerosene, the metal is effectively isolated from the surrounding oxygen, preventing oxidation and minimizing the risk of fire or explosions.

Water Isolation:
Sodium reacts vigorously with water, producing hydrogen gas and sodium hydroxide. This reaction is highly exothermic and can lead to the ignition of the hydrogen gas, further increasing the risk of fire or explosions. Kerosene, being non-polar and hydrophobic, acts as a barrier between sodium and water, preventing any contact between the two. This isolation ensures the safety of sodium and reduces the potential hazards associated with its reactivity.

Chemical Stability:
Kerosene is chemically stable and does not react with sodium under normal conditions. It serves as an inert medium, providing a protective environment for sodium while it is stored. The non-reactive nature of kerosene ensures that sodium remains stable and does not undergo any unwanted reactions.

Visually Appealing Summary:
In summary, sodium is stored in kerosene to prevent oxidation by isolating it from the surrounding oxygen and to prevent reactions with water. Kerosene acts as a barrier, ensuring the stability of sodium and minimizing the risks associated with its reactivity. By utilizing kerosene as a storage medium, sodium can be safely stored and handled in laboratory and industrial settings.
