Sodium metal reacts violently with water, and is stored in kerosine (for example) to avoid contact with moisture in the air.
sodium must be kept under kerosene
sodium will react with oxygen and kerosene will have no oxygen molecules in it
sodium
It is not necessary; sodium chloride is stable.
Sodium is very reactive, it can even react with water or air. So for this reason it is only kept in kerosene
Sodium is kept immersed in Kerosene oil because it's extremely reactive and will react with steam or any other substance. So as to obtain it in its pure form, it's kept in oil. Sodium is very reactive metal and it reacts with any thing that comes into contact with it.It is kept under the oil because it might react with air .
Sodium is metal. It is poisonous substance and also highly reactive. It catches fire when exposed in air.
When exposed to air or moisture, sodium will catch fire. Hence sodium cannot be kept in bottles on the shelf and generally sodium is kept inserted in non-polar solvents such as kerosene, pentane, hexane etc.
Why. Alkali. Metals are kept. In kerosene
Metals such as potassium and sodium react so vigorously that they catch fire if kept in open.Hence,to protect them and to prevent their burning they are stored in kerosene as moisture cannot enter in it.
Oxygen (which react with sodium) is not dissolved in kerosene.
Sodium reacts violently with water, so it must be kept from getting wet. Kerosene, being an oil, does a good job of protecting the sodium, and it is inexpensive and easy to come by.
