Question

why is phosphorus stored in water and why can't it be stoed in kerosene oil or any substance of such type

Answer 1

Phosphorous exist as P₄ which is a very strained molecule and thus it is very reactive also. It reacts with oxygen present in air and may ignite. Hence, it is kept in water to avoid its contact with air. It remain insoluble in water. However it is not kept in kerosene , oil , benzene etc because it is soluble in these solvents. Therefore can not be stored.
