Non-metal kept in kerosene:

Kerosene is a flammable liquid that is commonly used as a fuel. It is often used in lamps, stoves, and jet engines. When it comes to storing non-metals, kerosene can be used for certain non-metals that are highly reactive and can react with atmospheric oxygen or water vapor. One such non-metal that is commonly stored in kerosene is phosphorus.

Phosphorus:

Phosphorus is a non-metal that is highly reactive and combustible. It exists in several different forms, including white, red, and black phosphorus. White phosphorus is the most reactive and can spontaneously ignite in air at room temperature. It reacts vigorously with oxygen, resulting in the formation of phosphorus pentoxide.

To prevent the reaction of white phosphorus with atmospheric oxygen, it is stored in a liquid such as kerosene. Kerosene acts as a protective medium, preventing the contact of white phosphorus with oxygen and thus preventing its spontaneous ignition. By keeping white phosphorus immersed in kerosene, it remains stable and can be safely stored.

The use of kerosene as a storage medium for white phosphorus is crucial due to its highly reactive nature. White phosphorus can react with moisture in the air, leading to the formation of phosphoric acid, which is corrosive and highly toxic. Therefore, storing white phosphorus in kerosene helps to maintain its stability and prevents any unwanted reactions.

Precautions:

When handling white phosphorus, certain precautions need to be taken to ensure safety:

1. White phosphorus should only be handled in a well-ventilated area to prevent the accumulation of phosphorus vapor, which is highly toxic.
2. It should not be allowed to come into direct contact with skin or eyes, as it can cause severe burns.
3. Proper protective equipment, including gloves and safety goggles, should be worn while handling white phosphorus.

In conclusion, kerosene is used as a storage medium for highly reactive non-metals like white phosphorus to prevent their contact with atmospheric oxygen, which could lead to spontaneous ignition or the formation of toxic compounds. Storing white phosphorus in kerosene ensures its stability and allows for safe handling.
