when a 1.5104M aqueous solution of iron was extracted with CHCl3 containing 0.0250MHL, the analytical concentration of iron at pH 6.00 in the two phases were 1.0104M (upper [Fe3+] ) and 5.0105M (lower[FeL [F3] ). If 50.0mL of 1.00105MFe3+ in a pH 6.00 butfer were to be extracted with 25.0mL portions of 0.100MHL in CHCl2 how many extractions would be required to remove 99.5% of the iron from the aqueous phase A. 2 B. 4 C. 8 D. 3
