Q2:
Here you divide up the 100 mL of ligroin and use 25 mL freshphases in 4 passes on the aqueous phase
On first pass, x is determined to be 6.52 g. Nowyou have 10-6.52 g remaining in aqueous layer or 3.48 g
For the second pass with a new 25 mL fresh ligroin phase
Determine the new value of x and add this to 6.52....this sumis the amount extracted after two passes. Carry out thesame processes for the 3rd and 4th passes. The key is tocompare the total extracted in the 4 pass approach to the earlier 1pass approach to see which process effects the best separation.
Q3:
In the last question, you are told how much of A remains in theaqueous layer and how much remains in the ligroin layer. Youalso know the volume of water and you need to figure out the volumeof ligroin, Y.
Solve for Y. This is the volume of ligroin in mL to extract
