The separatory funnel on the left contains 50 mL of an aqueous solution of 0. 1 M I2 Extracting with 50 mL of CCla(bottom layer)shows a partial extraction of the lz into the CCla (note the purple color of l2 in CCla). A second extraction, as shown on the right, removes additional l2 from the aqueous layer. 2005-12 GXQ分析化学2005-2006学年 10化学化工学院 Analytical Chemistry 分析化学 2005-12 GXQ 分析化学 2005-2006学年 10
