Paper Chromatography

• What is the purpose of paper chromatography?

  To separate substances in a mixture based on their different solubilities.
• What are the key components of paper chromatography?

  • Chromatography paper (stationary phase)
  • Solvent (mobile phase)
  • Mixture of substances
• What type of process is chromatography?

  It is a physical process.
• Why are no new substances formed during chromatography?

  No new substances are formed because it is a physical process.
• What is the difference between the stationary phase and the mobile phase in paper chromatography?

  • Stationary phase: The paper that does not move.
  • Mobile phase: The solvent that moves up the paper.
• How does paper chromatography separate substances?

  By their different solubilities in the solvent.
• What indicates that a color is a pure substance in chromatography?

  A pure substance produces a single spot on the chromatography paper.
• What happens to a mixture of colors during paper chromatography?

  It separates into different spots based on solubility.
• What does a single spot in chromatography indicate about a color?

  It indicates that the color is a pure substance.
• How does the solubility of a substance affect its movement in paper chromatography?

  • More soluble substances are more attracted to the mobile phase.
  • They travel further up the paper than less soluble substances.
• What is the significance of the RF value in paper chromatography?

  It is used to identify a compound by comparing distances traveled.
