Vitamin B6 has a partition coefficient of 8.8 for water and chloroform. How many ml of chloroform is needed for a single extraction when the fraction of vitamin B6 that remains in 25ml water is the same as the fraction that remains (in 25 ml water) after a triple extraction with 10 ml chloroform?

Question

aaronq · Answer

hm so you're saying K=chloroform/water=8.8

when after triple extraction 10mL/25mL= 1

how much chloroform is needed for a single extraction?

How much chloroform is needed for the single extractin to get the same vitamin B6 fraction in 25 ml water as a triple extraction with 10 ml chrloroform
