Question

Why sodium is stored in kerosene not in other fuels?

Answer 1

Sodium is one of the most reactive metals mong the periodic table. It has a high electron losing tendency so that it completes the octet configuration of 2,8.Since water contains protons as H+ . Therefore sodium will lose one electron to the proton. And in this process a lot of energy is released. Therefore to cut the supply of moisture from air or any other source sodium is kept in kerosene.

Answer 2

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.
