    At 25 degrees C, 1.0 gram of caffeine will dissolve in 47 ml of water, in 8.1 ml's of chloroform, in 86 ml of benzene, or in 370 of diethyl ether. Calculate the partition coefficient of caffeine between water and each of the other three solvents. Which of these three organic solvents would be the best choice for extracting caffeine from an aqueous solution?

    How caffeine distributes between the solvents is based on the solubility of caffeine in each of the three solvents: more of it will be found in the solvent in which it is more soluble. The ratio of the concentrations of caffenie in each of the immiscible solvents is called the distribution coefficient or the partition ...
