Question

Using the formula below:

K= compound per mL organic solvent /compound per mL of water

(a) A compound distributes between benzene (solvent 1) and water (solvent 2) with a distribution coefficient, K = 2.7. If 1.0g of the compound were dissolved in 100mL of water, what weight of compound could be extracted by THREE sequential 10-mL portions of benzene?

b) one 30 mL portion of Benzene used

c) If the distribution constant, K, for the problem in part (a) were 0.5, for the distribution of a compound between benzene (solvent 1) and water (solvent 2), and equal volumes of the two solvents are used, how much compound will be left in the water after the three extractions.
