Detailed Solution

Storing sodium without a protective liquid like kerosene is extremely dangerous. Sodium is a highly reactive metal that reacts violently with oxygen and moisture in the air. This can cause spontaneous combustion, fire, or even explosions. Kerosene acts as a protective barrier, keeping sodium safe from air and water, and preventing these dangerous reactions.

Risks of Storing Sodium Without Kerosene

Spontaneous ignition: Sodium reacts quickly with air and moisture, often catching fire on its own.
Explosion hazard: When sodium contacts water, it produces hydrogen gas, which can ignite and explode.
Formation of harmful compounds: Reactions with oxygen and water form sodium oxides and sodium hydroxide, both of which release a lot of heat.
Excessive heat and light: These reactions are highly exothermic, creating intense heat and light, which can easily start a fire.

Why Kerosene Is Used for Storage

Inert protection: Kerosene is non-reactive, forming a safe liquid layer around sodium to keep out air and moisture.
Stable and long-lasting: It evaporates slowly, making it ideal for long-term storage.
High flash point: Kerosene doesn’t catch fire easily, reducing the overall fire risk during handling and storage.
