principles of classification

Carius method involves conversion of the halogen present in the organic compound into the corresponding silver halide. From the mass of the organic compound taken and the mass of silver halide formed, the percentage of halogen in the compound can be calculate..

The phosphorus present in an organic compound is oxidized to phosphoric acid by heating with fuming nitric acid. The phosphoric acid so obtained is precipitated as MgNH 4 PO 4 , which on ignition is converted into Mg 2 P 2 O 7 . From the mass of Mg 2 P 2 O 7 , the mass of phosphorus present in the..

Distillation involves the conversion of a liquid into its vapors upon heating and then cooling the vapors back into the liquid. Depending on the difference in boiling points of liquids, distillation is of two types: simple distillation and fractional distillatio..

This method is based on the fact that: Total vapor pressure above a mixture of two immiscible liquids is equal to the sum of the vapor pressures of the individual liquids i.e., P t o t a l = P 1 + P 2 Hence, P 2 = P t o t a l - P 1 A liquid boils at the temperature when its vapo..

This technique proceeds by a partly partition (distribution) and partly adsorption mechanism. The constituents of the mixture are distributed between the water held on the filter paper (water acts as a stationary phase) and organic solvent (mobile phase..

One mole of any volatile substance when vaporized gives vapor that occupy 22.4 L of volume under NTP condition..

A mixture of solid substances, such as camphor, benzoic acid, ammonium chloride, iodine etc., containing non-volatile substances, when heated, change directly into vapour without passing through the liquid stat..

When the fuel is ignited, combustion occurs. The liberated gases pass through the nozzle of the rocket motor, providing the necessary thrust for the rocket to lift and take of..

Difference in the boiling points of the various fractions of petroleu..

A positively charged particle can be accelerated to high energy with the help of an oscillating electric field, by making it cross the same electric field time and again with the use of a strong magnetic fiel..
