Resources Hint A chemist wants to extract a solute from 100 mL of water using only 300 mL of ether. The partition coefficient between ether and water is 2.82. Calculate q, the fraction of solute that would remain in the water under each of the extraction conditions. The chemist performs a single extraction with 300 mL of ether. The chemist performs three extractions with 100 mL of ether. The chemist performs six extractions with 50 mL of ether.

The extraction of 8.0 g of a particular organic compound dissolved in 100 ml of water into diethyl ether proceeds with a distribution coefficient of 5. How much of the compound is extracted after three separate extractions using 50 ml of diethyl ether each time? ***Please show work as I am not 100% sure how to solve for X**** Thank you!

1. An analyte has a partition coefficient of 2.0 between water and 1-pentanol. Given that 200 mL of a 5 % EtOH solution in water was extracted with 1-pentanol, calculate the fraction q of the analyte remaining in the aqueous phase (a) if one extraction of 200 mL is performed and (b) ten extractions of 100 mL are performed. (Hint: see page 49 in the manual. 2. For both 1a and 1b now calculate the Extraction Efficiency as a percentage

You have 100 mL of a solution of benzoic acid in water; the amount of benzoic acid in the solution is estimated to be about 0.30 g. The distribution coefficient of benzoic acid in diethyl ether and water is approximately 10. Calculate the amount of acid that would be left in the water solution after four 20-mL extractions with ether. Do the same calculation, using one 80-mL extraction with ether, to determine which method is more efficient.
