Vedclass · Answer

(A) Sodium and potassium are highly reactive metals. When kept in the open,they react vigorously with oxygen and moisture present in the atmosphere to form their respective oxides and hydroxides,releasing a large amount of heat. This heat is sufficient to ignite the metal,causing it to catch fire. Therefore,to prevent these reactions and accidental fires,they are stored immersed in kerosene oil,as they do not react with it.

What happens to potassium and sodium if they are kept in the open? Why are they immersed in kerosene?
