The image displays a chromatography experiment with two diagrams labeled "before" and "after." **Before Diagram:** - Four dots labeled as **X**, **Y**, **Z**, and **sample** are aligned horizontally near the bottom of the diagram, indicating the initial placement of substances on a chromatography paper strip. **After Diagram:** - The vertical scale on the left measures height in centimeters from 0 to 6. - The **origin line** is marked at the bottom, where the substances were initially applied. - The **solvent front** is a horizontal line near the top, showing the highest point reached by the solvent on the strip. - The substances **X**, **Y**, **Z**, and **sample** have moved up the strip, each forming distinct spots at various heights. This illustrates the separation of mixtures via chromatography, where different components travel different distances based on their affinity to the solvent and paper.
