Mar 17, 2021 · WHAT IS CHROMATOGRAPHY? Chromatography is a technique used to separate mixtures. Information from a chromatography investigation can also be used to identify different substances. In chromatography, the mixture is passed through another substance, in this case, filter paper.

Apr 11, 2022 · Use these free STEM lessons and activities to experiment with paper chromatography. Chromatography is a technique used to separate a mixture or solution into its individual components. There are several different types of chromatography, including thin-layer, column, and paper chromatography.

Feb 24, 2025 · Chromatography separates substances into their components. All forms of chromatography work on the same principle. They all have a stationary phase (a solid, or a liquid supported on a solid) and a mobile phase (a liquid or a gas).

Sep 28, 2021 · How Leaf Chromatography Works. Paper chromatography separates pigments in leaf cells on the basis of three criteria: Solubility; Molecule size; Polarity; Solubility is a measure of how well a pigment molecule dissolves in the solvent. In this project, the solvent is alcohol. Crushing the leaves breaks open cells so pigments interact with alcohol.

Apr 24, 2017 · Chromatography is a method you can use to separate and analyze the individual components of complex mixtures, ranging from ink to amino acids to vapors. Chromatography requires a stationary phase as an immovable platform that the mobile phase -- the water or other solvent to carry the mixture to be separated -- moves through.

Apr 23, 2020 · Have you ever looked at sunlight through a prism or drops of water? If so, you know that the prism can separate the sunlight into many different colors of light — a rainbow. Like sunlight, chemical mixtures can also be broken into their component parts. One way of doing this is a simple technique called paper chromatography.

Oct 15, 2022 · To use paper chromatography to identify whether certain colored inks are pure substances or mixtures. Chromatography is a method of physically separating mixtures into its individual components. It is a common laboratory technique …

Apr 16, 2020 · Chromatography is yet another technique for the analysis and separation of chemical mixtures. The technique is based on a polarity interplay between the sample and two other substances called the solid (or stationary) phase, and the mobile phase, which can be a …

Chromatography can be used to separate a mixture of soluble substances. Find out more with this guide for KS3 chemistry students aged 11-14 from BBC Bitesize.
