Sodium is a highly reactive metal that readily reacts with water to form sodium hydroxide and hydrogen gas. This reaction is exothermic and can lead to the release of heat and potentially cause the hydrogen gas to ignite, resulting in a fire hazard. Additionally, sodium reacts with oxygen in the air to form sodium oxide, which can further exacerbate its reactivity.

By immersing sodium in kerosene oil, a non-polar solvent, a protective layer is formed around the metal. This layer acts as a barrier, preventing moisture and oxygen from coming into contact with the sodium. As a result, the risk of uncontrolled reactions and potential hazards is significantly reduced.

Handling sodium requires careful consideration of safety precautions due to its reactivity. Keeping it immersed in kerosene oil not only protects the metal but also ensures the safety of those working with it. Proper storage and handling of sodium are essential to prevent accidents and maintain a safe working environment.

Despite its reactivity, sodium finds various applications in industries such as pharmaceuticals, organic synthesis, and even in some types of batteries. By storing sodium in kerosene oil, its reactivity can be controlled, allowing for safe handling and utilization in these applications.
