(Points : 3)
chromatography

simple distillation

fractional distillation

filtration

Answer 1

Answer: chromatography

Step-by-step explanation:

Chromatography : It is a type of separation process in which the liquid or gas is separated into components at different rate. The principle of chromatography is that the substance of molecule are distributed between the liquid phases. It involves a stationary and a mobile phase. Hence,chromatography is a laboratory technique that is used to separate plant pigments.

Distillation : It is a type of separation process in which the mixture of liquid separated or evaporated at different temperatures.

Fractional distillation is separation of a liquid mixture into fractions which differ in boiling points by means of distillation by use of a fractionating column.

Filtration : It is a type of mechanical separation process in which the solid is separated from the liquid through the filter paper.

Answer 2

Chromatography is the technique used to separate mixtures into the components that make up those mixtures. In chromatography the different pigments are separated into bands of pigment through their differences in intermolecular forces.
