Question Answered step-by-step C. During the chromatography experiment, a pigment moved 1.5 cm,… C. During the chromatography experiment, a pigment moved 1.5 cm, another 3.0 cm and another 4.6 cm whilst the solvent had moved 4.8 cm. The data collected is shown in table 12 below. Calculate the retention factor (Rn values of the pigments and give your answer to two significant figures. Place your answers in table 2 below. Show your working out.RF is equal to distance traveled by pigment in cm/ distance travelled by solvent in cm(6 marks)Table 2: Experimental resultsPigment distance Solvent distance Rf value 1.5 4.8 3.0 4.8 4.6 4.8 D. The literature reports the following Rf values for each component using the same solventRf 0.63 for xanthophyll,Rf 0.15 for chlorophyll b,Rf 0.31 for chlorophyll a, andRf 0.95 for ß-carotene. Identify your pigments with this data and draw a bar chart to represent their Rf values.(5 marks)E. Draw conclusions for the experiment from your graph. (2 marks)F.
