Here are the solutions to the questions: 1. i) Which of the three pure pigments is most sticky? Give a reason for your answer. Pigment A. Reason: It traveled the shortest distance from the baseline, indicating it has the highest affinity for the stationary phase (filter paper) and/or lowest solubility in the mobile phase (ethanol). 1. ii) Which pure pigment is not present in the mixture F? Pigment C. Reason: The highest spot in mixture F does not reach the same height as the spot for pure pigment C. 1. iii) label on the diagram the base line The baseline is the horizontal line at the bottom of the chromatogram, where the spots A, B, C, and F are initially
