(a) How will you separate the components of ink using chromatography? Explain with
the help of a labelled diagram
(b) What is the function of glass beads present in fractionating columna
(which method out of evaporation and crystallisation is a better technique to separate
sugar from surar solution Give reasons also
Answers
Answer:
It can be used to separate mixtures like ink, blood, gasoline, and lipstick. In ink chromatography, you are separating the colored pigments that make up the color of the pen. ... The solvent moves up the paper strip and, as it travels upward, it dissolves the mixture of chemicals and pulls them up the paper.
a) Chromatography can be used to separate fusions of coloured composites. fusions that are suitable for separation by chromatography include inks, colorings and colouring agents in food.
Simple chromatography is carried out on paper. A spot of the admixture is placed near the bottom of a piece of chromatography paper and the paper is also placed upright in a suitable detergent, eg water.
As the detergent soaks up the paper, it carries the fusions with it. Different factors of the admixture will move at different rates. This separates the admixture out.
b) The glass globules present in the fractionating column give a large face area for hot vapours to cool and condense constantly. The fractionating column is fitted in the neck of the distillation beaker containing the admixture of liquids to beseparated.Sugar can be separated from its result by using both evaporation and crystallization. But crystallization system is preferred over evaporation because in crystallization we get pure chargers of sugar whereas in evaporation charring of sugar can takes place.
