Questions and Answers
What should be ensured about the solution level on the chromatography paper?
What occurs when spots of the same color are analyzed at lower concentrations of isopropanol compared to higher concentrations?
What is the appropriate action to take after the chromatography strips have developed?
Study Notes
Paper Chromatography Procedure
- Place paper strips in beakers, ensuring the solution level is below the start line.
- Cover beakers to prevent evaporation.
- Allow strips to develop until the ascending solution front reaches 2 cm from the top of the strip.
- Remove and dry strips after development.
Observations and Results
- Some dyes are composed of multiple colors, as revealed by chromatography.
- Spots of the same color separate more efficiently in lower isopropanol concentrations compared to higher concentrations.
- Different colored spots begin separating at distinct concentrations of isopropanol.
