The distribution coefficient between methylene chloride and water for solute Y is 9. An amount of 125.0.0 g of Y is dissolved in 160 mL of water.
a) What weight of Y would be removed from water with a single extraction with 160-mL of methylene chloride? Report to 1 decimal place.
b) What weight of Y would be removed from water (the original solution with the original amount) with two successive extractions with 80-mL portions each of methylene chloride? Report to 1 decimal place.

1) 3-Fluorophenol has a pKaof 8.40. 4-Nitrophenol has a pKa of 7.16. 3-Chlorobenzoic acid has a pKa of 3.82. You will need the following information: The pKa of HCl is –7; pKa of carbonic acid is 6.52 and the pKa of water is 15. a) You have a mixture of 3-fluorophenol and 4-nitrophenol that you wish to separate by extraction. The mixture is dissolved in methylene chloride. Why would reacting the mixture with an aqueous solution of NaHCO3NOT separate one...

Suppose solute A has a distribution coefficient of 1.0 between water and diethyl ether. Demonstrate that if 4.0 mL of a solution of 0.20 g of A in water were extracted with two 1.0-mL portions of ether, a smaller amount of A would remain in the water that if the solution were extracted with one 2.0-mL portion of ether.
