Why sodium metal kept immersed in kerosene oil?

Question

Answer

Sodium immersed in kerosene oil because sodium is a reactive element that can burn in air.

Answer

Because it's highly reactive metal...it react with air rapidly... so we keep it in kerosene to prevent it from air

Answer

As sodium is the highly reactive element and when it come in contact with air it burns vigorously in air as it was an highly exothermic reaction.

Answer

Because it is highly reactive

Answer

Sodium metal is kept immersed in kerosene oil to prevent accidental fire.
It is very reactive metal and combines explosively with air as well as water. It will catch fire if kept in open.
Note: Potassium is also kept immersed in kerosene oil for same reason.

Answer

When sodium is react with oxygen are vigorously catch fire. it is a high reactive Metal that's why sodium is always kept under the kerosene oil.

Answer

Sodium is highly reactive and reacts with air

Answer

Sodium is very reactive metal.It is kept in kerosene to prevent it from coming in contact with oxygen&moisture.Sodium react with oxygen to form sodium hydroxide which is strongly exothermic reaction and during this reaction a lot of heat is generated.

Answer

Why is Sodium Metal Kept Immersed in Kerosene Oil?

Sodium is a highly reactive metal that readily reacts with moisture and oxygen in the air, leading to oxidation and the formation of sodium oxide and sodium hydroxide. To prevent this reaction and protect the sodium from coming into contact with air and moisture, it is commonly stored in an inert medium such as kerosene oil.

Explanation:

Reactivity of Sodium:
Sodium is an alkali metal that is highly reactive due to its electronic configuration. It has one valence electron in its outermost shell, which it readily donates to achieve a stable electron configuration. This reactivity makes sodium highly reactive with water, oxygen, and other substances.

Reaction with Air and Moisture:
If sodium is exposed to air or moisture, it rapidly reacts with the oxygen and water vapor present. This reaction leads to the formation of sodium oxide (Na2O) and sodium hydroxide (NaOH). Sodium oxide is a white solid, while sodium hydroxide is a caustic, corrosive substance.

Formation of Sodium Oxide:
2Na + O2 → Na2O

Formation of Sodium Hydroxide:
2Na + 2H2O → 2NaOH + H2

Role of Kerosene Oil:
Kerosene oil serves as an excellent medium to store sodium due to its properties.

Inert Nature:
Kerosene oil is an inert substance that does not react with sodium. It forms a protective layer around the sodium metal and prevents it from coming into contact with air and moisture. This inert nature of kerosene oil ensures the preservation of sodium's metallic properties.

Viscosity:
Kerosene oil has a relatively high viscosity, which means it is thick and sticky. This property helps in containing the sodium metal and preventing it from dispersing or reacting with the surrounding environment.

Insolubility:
Sodium is insoluble in kerosene oil, further ensuring its stability and preventing any unwanted reactions. This insolubility ensures that the sodium metal remains intact and does not dissolve or disperse in the storage medium.

Conclusion:
In summary, sodium metal is kept immersed in kerosene oil to protect it from the reactive elements in the air and moisture. The inert nature, viscosity, and insolubility of kerosene oil create a suitable environment for preserving the metallic properties of sodium and preventing any unwanted reactions.

Answer

Bcoz it is a high reactive metaldue to its monovalency so it looses electron easily even in open air and react with oxygen to form Na2O, NaO for stable.

Answer

Because sodium is a very highly reactive metal and when exposed to air it vigorously react with air to fom its oxide.

Answer

To cut oxygen supply as it can get its ignition temperature at normal room temp.

Answer

Because sodium is very reaction which catches fire when it come in contact of air so it kept immersed in kerosene.
if u write this answer in ur notebook do not start with because if u do so it will deduct ur marks.

Answer

It is very reactive it reacts with oyygen even in room temperature

Answer

Because
