Question

why do we store sodium and potassium in kerosine, while phosphorus in water

Answer 1

Sodium is highly reactive metal.

Sodium reacts with oxygen in air at room temperature to form sodium oxide.

Sodium reacts with water to evolve hydrogen which immediately catches fire.

In ordinary air, sodium reacts with to form a Sodium Hydroxide film, which can rapidly absorb carbon dioxide, forming sodium bicarbonate.

Sodium does not react with kerosene.

Its density is greater than kerosene.

Hence,sodium is stored under kerosene.

Same goes for Potassium,it is also stored under kerosene.

HERE'S YOUR ANSWER ⬇️⬇️⬇️

Because they are reactive elements. Sodium reacts with water or air and hence needs a medium like kerosene. Phosphorous reacts with air and thus can be stored in water.
