mixtures solutions and suspensions

A suspension is a heterogeneous mixture in which one or more components have a particle size greater than 10 - 5 cm. Very often these particles are visible to the naked eye. For example, sand in water, sodium chloride in benzene, turmeric in water et..

A mixture is a combination of two or more elements or compounds in any proportion so that the components do not lose their identity. Air is an example of a mixture (several gases mix to form air). Mixtures are of two types, homogeneous and heterogeneous. Homogeneous ..

A true solution is a homogeneous solution in which the solute particles have diameters less than 10 - 7 cm. i.e., the solute particles are of molecular dimensions. The particles are invisible even under powerful microscopes. For example, sodium chloride in wa..

Azeotropic Mixtures - In case of solutions showing positive deviation from Raoult's law, at one of the intermediate compositions, the total vapor pressure is the highest and the boiling point is the lowest. Similarly in case of solutions showing negative deviations fro..

Distillation is a method used to separate a solute and a solvent from a solution. In evaporation, vaporization takes place and only the solute is obtained. However, distillation is actually a combined process of vaporization and condensation. In distillation, bot..

Crystallisation is the process by which crystals are obtained from a saturated solution of a substance, by allowing the solvent to evaporate slowly. If there are any insoluble impurities in the solution, they can be removed by filtration. Then by slow evaporation pure crys..

Impure Substances - Mixtures - "Impure substances are commonly called mixtures." The constituents of a mixture may be elements, compounds, or both. These substances may be present in any proportion and exhibit their individual properties. Mixtures can be homo..
