In Louisiana (USA) and Gulf of Mexico large sulphur deposits occur at a depth of about 300-400 metres below the earth's surface. Layers of soft sand, clay and rocks over these sulphur beds make it practically impossible to extract sulphur from the deposits. Hermen Frasch in 1894 devised ..

Mining of Sulphur - Frasch Process A Frasch pump consisting of a set of three concentric pipes is sunk deep into the sulphur bed Super heated water at 170 0 C under pressure is pumped in through the outermost pipe Sulphur in the sulphur bed melts due to i..

1) 1 s t step - Catalytic oxidation of ammonia to form nitric oxide 2) 2 n d step - Oxidation of nitric oxide to nitrogen dioxide. 3) 3 r d step - Absorption of nitrogen dioxide in water to give nitric acid...

Combustion is a chemical reaction in which burning of substances takes place. In this process, a substance combines with oxygen to burn (decompose) itself liberating heat and sometimes light and flame. Thus, combustion reactions are exothermic or heat dissipating..

The identification and characterization of an organic compound such as molecular formula etc., must have the compound available in pure form. The process of obtaining the compound in its purest form from an impure sample or from any reaction mixture is called purification...
