If the impure compound is a mixture of two compounds whose solubility in any solvent does not differ significantly from one another, then the two compounds are separated by fractional crystallization. This is a series of repeated crystallisations. For instance when a solution containing ..

Crude petroleum is pumped into the furnace where it is heated to a temperature of about 400 o C. Petroleum is converted to vapours in the furnace. The vapours of petroleum are fed into the fractionating column from the bottom. As the vapours enter the column, they rise up and grad..

Water for All - Water is a unique and remarkable compound, essential to all forms of life. Human beings and the flora and fauna cannot survive without water on this planet. A large amount of life on this planet is aquatic based i.e., can only survive in water. It is the most abundant substance afte..

Summary - Dalton had postulated that matter is made up of atoms, which are indivisible. Thomson was the first to suggest a structure for an atom. According to him, an atom is a positively charged sphere of radius=10 - 1 0 m in which the mass and the positive charge of the atom are uniformly distrib..
