Kerosene is composed of saturated hydrocarbons, with which sodium and potassium do not react. They do react rapidly, however, with the water vapor and oxygen in air and therefore must be protected from it in order to remain in elemental form.
The following excerpt from an earlier answer to this question, "[sodium] is unsaturated hydrocarbon . eventhough sodium is highly reactive it doesn't reacts with oxygen when Na++ is preserved in kerosene. hence," is wrong from beginning to end and should be ignored.
Sodium metal is stored in kerosene or light oil distillates because it doesn't react with those compounds. It has to be isolated from water and air, as it highly reacts with water and with oxygen in the air.
Sodium and Potassium react vigourously with air which prevents it to be stored outside kerosine.
I assume many oils would be effective in keeping these metals away from the air they are explosively reactive in.
Sodium reacts rapidly with water and is therefore unstable in contact with it.
To keep them from touching air or water. If they touch air they will oxidize, which can ruin a sample. IF they touch water they can burst into flame.
This is done to prevent the acces of oxygen and also humidity (water vapor) from air to sodium metal.
If not then sodium will BURN (self ignition).
Sodium and Pottasium are metals reacts violently, and is stored to avoid contact with moisture in the air.
Sodium and potassium are stored under kerosene because it is highly reactive to air so its is flammable
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 .
it comes in contact with air
sodium and potassium are kept under kerosene surface to protect them from rust since the are very active elements and react with O as soon as being exposed to it.
Yes, it has to be stored in kerosene oil or it will catch fire.
pottasium chloride have two atoms, i.e. one of potassium and one of chlorine
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

fehling a is copper sulphate and fehling b is alkaline solution of sodium pottasium tartarate
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.
Why. Alkali. Metals are kept. In kerosene
Oxygen (which react with sodium) is not dissolved in kerosene.
