Compound A is three times more soluble in diethyl ether than in water, so its partition coefficient is K = 3, for partitioning of Compound A between diethyl ether and water. for a sample of compound a dissolved in 50mL of water, answer the questions: 1) Determine the fraction of A that remains in the water, FA, after one extraction with 200mL of diethyl ether. 2) Determine FA after two extractions, using 100mL of diethyl ether in each of the...
Extractions rely on differences in solubility of the components that are being separated. The amount of a material that will transfer into the solvent in an extraction can be calculated using a partition coefficient. This is a ratio of the solubility of the material in each solvent that can be used to predict outcomes of extractions. A certain organic compound, Z, has the distribution coefficient (partition coefficient), Kp = 10.45 when partitioned between ether and water. Therefore, the equation used...
Solute A has a partition coefficient of 8 between toluene and water. Suppose that 350 mL of a 0.01 M aqueous solution of A are extracted with toluene. What would be the extraction efficiency (R%) if 2 extractions with 50 mL toluene were performed? (Keep one decimal place in your final answer.)
