why pottassium and sodium kept in oil ?

Asked by darsanasanjeev | 23rd Nov, 2014, 10:58: PM

Expert Answer:

Both potassium and sodium are highly reactive and catch fire when exposed to oxygen in air. Only oil such as kerosene cut off the contact of these metals with oxygen in air. Hence both the metals are kept in oil.
