[問題] 想要問一下化學的問題 希望有人可以幫忙回答 …
1.A solute with a partition coefficient of 4.0 is extracted from 10 mL
of phase 1 into phase 2.
(A)What volume of phase 2 is needed to extract 99% of solution in one
extraction?
(B)What volume of phase 2 is needed to remove 99% of solution
in three equal extractions instead?
2. Suppose that the partition coefficient for an amine, B, is 0.33
and the acid dissociation constant of BH+ is Ka=1.0x10-9.
If 50 mL of 0.010M aqueous amine is extracted with 100 mL of solvent.
What will be the formal concentration remaining in the aqueous phase
(1) at pH 10.0? (2) 8.0?
因為困惑 所以想要請人幫忙解答 謝謝!! ^^
