Question

Why do we store potassium in kerosene ?

Answer 1

Sodium and Potassium are highly reactive metals, they catch fire when kept in open

.and a lot of heat is given out which can prove harmful for us.

also their is low so they float on water which makes them to come in contact with air.

Since, the density of kerosene is also low both of them do not float on kerosene.

Kerosene is sooo saturated that they both do not react with kerosene.

So they are kept immersed in kerosene oil.
