method of separation of variable

The separation of mixtures into its constituents in a pure state is an important process in chemistry. The constituents of any mixture can be separated on the basis of their differences in their physical and chemical properties e.g., particle size, solubility, effect of heat, a..

When the (+) and (-) isomers or their salts form well defined crystals showing hemihedral faces, hand picking is used to separate them. Pasteur separated sodium ammonium racemate crystals by mechanical separation in 1848. Below a certain temperature the enantiomorphs ..

Magnetic ores like pyrolusite (MnO 2 ) and chromite (FeO.Cr 2 O 3 ) are enriched by this method by making use of the difference in the magnetic properties of the ore and gangue particles. ..

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, both the solv..

Chromatography is a method of separating and identifying various components in a mixture, which are present in small trace quantities. There are several types of chromatography, one of which is paper chromatography. It is extensively used in research and industry, to analyse and..

If the integrand f(x) of the integral is not in an integral form the variable of integration x is changed to a suitable variable z by substitution and on differentiation and simplification, the new integral is found integrable. ..

The finely powdered ore is fused with a mixture of barium carbonate, barium sulphate and potassium sulphate. The fused mass is separated into two layers, the upper layer consists of lithium, sodium and potassium sulphates and the lower layer consists of barium sulphate, alumina and silic..

This method is also known as tabular method. In this method, a set is represented by listing all the elements of the set, the elements being separated by commas and are enclosed within flower brackets {..
