Paper Chromatography: Separating Mixtures with Science

How does paper chromatography work?

Option 1: By using heat and pressure

Option 2: By mixing chemicals together

Option 3: By separating components of a mixture

Option 4: By analyzing the color of a substance

Final answer:

By separating components of a mixture

Explanation:

In paper chromatography, substances in a mixture are separated based on their affinity to the mobile phase (solvent) and the stationary phase (paper). As the solvent moves up the paper, it carries different components of the mixture at different speeds, resulting in separation. Paper chromatography is a powerful technique used in laboratories for analyzing mixtures, identifying unknown substances, and determining the purity of compounds.
