उत्तर
Chromatography is a separation technique used to separate the different components in a liquid mixture. Separation of substances by chromatography is based on two properties of the substance:
- the solubility of the substance in the solvent that moves up.
- the ability of the substance to stick to the stationary filter paper.
These properties are different for different substances and are mutually opposite to each other. It is the reason why all the components of the mixture rise up to a limited height when the water rises up to the upper end of the paper.
