An unknown mixture (dissolved in diethyl ether) contains only 2 of the following : benzoic acid, phenol, aniline and napthalene. You use the acid-base extraction method and want to identify the 2 compounds in your original mixture. 1) To separate the organic acid you add NaOH and to separate the organic base you add HCl.In both cases these extractions are followed by extractions with water. Why do we add water? Why is this step important? (A clear explanation please). 2)When...

Acid/Base Extraction Liquid-liquid extraction is a technique that can be used to physically separate two substancesthat have varying solubility properties. Typically an aqueous solution can be extracted with anorganic solvent to isolate a compound or vice-versa. The specialized piece of glassware that isemployed for these types of separations is called a separatory funnel.In this experiment a mixture of benzoic acid and naphthalene will be purified using liquid-liquidextraction, more specifically an acid-base extraction. Since both compounds are soluble inethyl acetate (an...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
