Answer:A mixture of unknown amino acids can be separated and identified by means of paper chromatography. The position of the amino acids in the chromatogram can be detected by spraying with ninhydrin, which reacts with amino acids to yield highly coloured products (purple).
Paper chromatography is a method of separating and analyzing a mixture For example, simple paper, chromatography can be used to separate a mixture of dyes. The filter paper, which contains a thin film of water trapped on it, forms the stationary phase. The solvent is called the mobile phase or eluant.
