Question

(a) What is fractional distillation? What is the use of fractionating column in fractional distillation?
​(b) Draw a labelled diagram of the fractional distillation apparatus used for separating a mixture of alcohol and water.

Answer 1

Answer:

the process of separating the parts of a liquid mixture by heating it. As the temperature goes up, each part in turn becomes a gas, which then cools as it moves up a tube and can be collected as a liquid

द्रव-मिश्रण को तपा कर उसके अंश-विभाजन की प्रक्रिया, ताप बढ़ने के साथ प्रत्‍येक अंश गैस में बदल जाता है और फिर ठंडा होकर नली में से गुज़रते हुए द्रव बन जाता है

Answer 2

Answer:

Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize.

 fractionating column is an essential item used in distillation of liquid mixtures so as to separate the mixture into its component parts, or fractions, based on the differences in volatilities.
