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.
