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!! ^^ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.115.84.42 ※ 編輯: violetpink 來自: 59.115.84.42 (11/04 15:10)
