Question

Why are the elements sodium and potassium kept in kerosene ?
​

Answer 1

Sodium and potassium metals are kept in kerosene or in dry mineral oil. ... In summary, these metals are stored in kerosene because kerosene contains no water and protects these metals from being exposed to any moisture in the air that would cause these metals to react, potentially violently.

Answer 2

Answer:

sodium (Na) and potassium (K) are violently reactive metals because of their electropositivity (tendency to loose electrons ) and hence reactive to form compounds.

Explanation:

They violently react with water causing explosion. Thus to avoid this, they are stored in kerosene.
