Why sodium and pottasium are kept in kerosene?

Answer 1

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.

Answer 2

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.

Answer 3

Sodium and Potassium react vigourously with air which prevents it to be stored outside kerosine.

Answer 4

I assume many oils would be effective in keeping these metals away from the air they are explosively reactive in.

Answer 5

Sodium reacts rapidly with water and is therefore unstable in contact with it.

Answer 6

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.

Answer 7

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).

Answer 8

Sodium and Pottasium are metals reacts violently, and is stored to avoid contact with moisture in the air.

Answer 9

Sodium and potassium are stored under kerosene because it is highly reactive to air so its is flammable
