Chloroform is used to extract caffeine from water.If the distribution coefficient, KD=10.What relative volume of chloroform-water should be used to extract 90% of the caffeine present in one single extraction?
Now i know that KD=Co/Cw and I've solved a question on how much weight of an acid will be removed by extraction.But I'm lost here..don't i need the solubility of the products to solve this?
