Why is sodium kept in kerosene oil?

Question

Answer

It is highly reactive and reacts with o2 present in atmosphere and catches fire . so it is kept in kerosene. kerosene is type of oil that prevent air to enter in it hence. we keep it in kerosene.

Answer

Sodium is stored in kerosene as it is very reactive and can catch fire if kept open

Answer

Introduction:

Sodium is a highly reactive metal that oxidizes rapidly when exposed to air. To prevent its reaction with moisture and oxygen present in the air, sodium is typically stored under kerosene oil. This method of storage helps to preserve the reactivity of sodium and ensures its safe handling.

Reasons for storing sodium in kerosene oil:

1. Protection from moisture:
When sodium comes into contact with moisture, it reacts vigorously and releases hydrogen gas. Storing sodium in kerosene oil prevents its exposure to moisture in the air, as kerosene is immiscible with water. The oil forms a protective layer on the surface of sodium, acting as a barrier against moisture and preventing the reactive metal from reacting with water vapor in the air.

2. Prevention of oxidation:
Sodium is highly reactive and readily reacts with oxygen present in the air, forming sodium oxide (Na2O). By keeping sodium submerged in kerosene oil, the metal is isolated from the oxygen in the air, which helps prevent oxidation. This ensures that the metallic properties of sodium are preserved, allowing it to retain its reactivity.

3. Safety during handling:
Storing sodium in kerosene oil also provides safety benefits during handling. Since sodium reacts violently with water, exposing it to even a small amount of moisture can lead to hazardous situations. The kerosene oil acts as a protective medium, reducing the risk of accidental reactions. It also helps to control the rate of reaction if any small amount of moisture does come into contact with the sodium.

4. Visual indication:
The use of kerosene oil for storing sodium also provides a visual indication of the presence of the metal. Sodium stored in kerosene appears as a shiny, metallic substance submerged in the oil. This aids in identifying the presence of sodium and ensures that proper precautions are taken while handling it.

Conclusion:

Storing sodium in kerosene oil offers multiple advantages. It protects the metal from moisture, prevents oxidation, enhances safety during handling, and provides a visual indication of the presence of sodium. These measures help to maintain the reactivity and integrity of sodium, making it suitable for various applications in laboratories and industrial settings.

Answer

Because sodim is highly reactive metal and hence we kept it in kerosene
