mixing instead of vigorously shaking them will help prevent emulsions from forming in the first place.1. Questions1. You are given a substance that is equally soluble in water and hexane (two immiscible solvents).a) What is K?b) If you start with 10 g of the substance dissolved in 100 mL of water and are given 100 mL ofhexane to extract with, algebraically show that it is better to do two smaller extractionsusing 50 mL of hexane for each extraction than it is to do one extraction using 100 mL ohexane.2. You have a solution that contains 4.0 g of oxalic acid dissolved in 100 mL of water. This solution isplaced in a separatory funnel, and then 100 mL of diethyl ether is added to the separatoryfunnel and an extraction is performed. (Diethyl ether and water are immiscible solvents.) Use thefollowing constants to calculate how much oxalic acid is in each solvent after the extraction.Solubility of oxalic acid in water = 9.5 g / 100 mLSolubility of oxalic acid in ether = 16.9 g / 100 mL3. Briefly describe how you can tell which layer is the aqueous phase after performing an extraction.4. Could you use methanol instead of methylene chloride to do a liquid-liquid extraction of anaqueous solution? Briefly explain why or why not.T5-12
