What is kerosene?

Shruti said:   6 years ago
Sodium is highly reactive metal. It reacts with water vapour and as a result of it, a large amount of heat is liberated which can lead to a fatal accident. Sodium does not react with kerosene hence it is kept in kerosene.

Sodium is a silvery white metal belonging to Group1 of the Periodic Table, which is the alkali metals group. Sodium is highly reactive. The pure metal is kept under oil or kerosene because it spontaneously ignites in water. It's interesting to note that sodium metal also floats on water!Room temperature sodium metal is soft enough that you can cut it with a butter knife.

Because it has low ignition temperature, even low than room temperature, at room temperature it react with Oxygen.

Sodium oxidized instantly on exposure to air and reacts violently with water, yielding sodium hydroxide and hydrogen gas. Hence it is preserved under kerosene.

Why only kerosene but? why not Alcohol?

Sodium reacts with air and form following reaction

Na+H2O(IN THE PRESENCE OF O2)=NaOH+H2

So avoid raection with H2o & O2 Na kept in kerosene oil.

Because it react with H2O and burned and form H2 vigorously. In air trace amount of water present.

AS sodium is highly reactive, it reacts with oxygen vigorously to form sodium peroxide when exposed to air. Hence it is stored under kerosene.

Sodium is most reactive element hence it reacts vigorous that's why some traces kept in kerosene.
