"Liquid-Liquid Extraction" Post-lab Questions (14 points) The following data table comes from: Edwards, Lunat, Garner-O'Neale, and Kulikov, Distribution of Caffeine between Selected Water-Organic Solvent Media, Int. J. Chem. Sci. 13(3), 2015, 1218-1226. Estimate the partition coefficient for ethyl acetate as K-02. 12- 10 Fig.2: Mean (n-2: ± SD) K. values obtained for the LLE of caffeine from water using various organie solvents at 25°C 4. Based on the chart above, would chloroform be a better or worse solvent for the extraction of caffeine? Explain.Explanation / Answer
According to the data, Chloroform is a better solvent for the extraction of Caffiene
Since solubiliyt of caffiene is high, hence on adding chloroform to the caffeine solution, the caeffiene will be transferred to the chloroform
Now, the chloroform-caffeine mixture can be seperated easily based on the density difference between the two compounds
