LSC S1:Elements, Compounds and Mixtures

water remains as the residue since it has a higher boiling point of 1000C. If a mixture contains many components each of which has a different boiling point, they can be separated in fractions. Hence this method of separating mixtures is known as fractional distillation. This method of separating mixtures is relevant during the manufacture of gases like oxygen. Oxygen and nitrogen and purification of crude oil, petrol, diesel and gas are collected at different boiling points.
