Answer:
Paper chromatography
Paper chromatography is another method that can be used to test if a substance is pure or impure. It can also be used to separate mixtures of soluble substances in order to find out what substances are in the mixture. These are often coloured substances such as food colourings, inks, dyes or plant pigments.
