sodium will react with oxygen and kerosene will have no oxygen molecules in it
sodium
sodium must be kept under kerosene
Sodium is metal. It is poisonous substance and also highly reactive. It catches fire when exposed in air.
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.
phosphorous is kept immersed in water because it reacts with air.
sodium
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 must be kept under kerosene
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
Because is reacts with water causing hydrogen to be released and catch fire. Na + H2O = NaOH + H also it will also float on water having a density of 0.98 g/cm^3
Sodium metal reacts violently with water, and is stored in kerosine (for example) to avoid contact with moisture in the 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.
When exposed to air or moisture, sodium will catch fire and explode. So it is kept immersed in an inert or non-polar solvent (such as hexane, pentane) to prevent its contact with air or moisture.
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.
