Paper chromatography
Paper chromatography is an analytical chemistry technique for separating and identifying mixtures that are or can be coloured, especially pigments. This can also be used in secondary or primary colours in ink experiments.
To make our experiment we need paper, some colored ink, a glass of water, salt and alcohol.
