Explanation:
Na and K are very reactive metals and kept in
kerosene oil to prevent it from coming in contact
with oxygen and moisture as they react to form their
hydroxides. This is an exothermic reaction and lot
of heat is generated so both the metals are kept in
kerosene oil.

Sodium is stored in kerosene for the following reasons;-
1. Sodium reacts with water vigorously. Sodium is stored in kerosene because it does not contain any water. So there is a lesser chance that Sodium will react vigorously with water when kept under the environment of kerosene oil.
2. Sodium reacts with oxygen/air vigorously. Sodium is stored in kerosene because it does allow air/oxygen to enter its environment. So there is a lesser chance that Sodium will react vigorously with air/oxygen when kept under the environment of kerosene oil.
