Question
If 50 mL of an aqueous solution containing 10 g of A is mixed with 100 mL of diethyl ether, how many g of A will be transferred to the organic layer? (K is still the same, but there is twice as much ether as water.)Compare the amount of A extracted by two extractions using 50 mL of diethyl ether each to the amount extracted by a single 100 mL extraction of the ether. Which is more efficient?Explanation / Answer
10 g of A in 150 mL of solution......Let X amount of A be in the aqueous layer...=> 2.8 X + X = 10 ......=> X = 7.37 g = Amount of A in ether......Therefore using 2 extractions is more efficient
