A Freezing-Point Depression experiment is done using 2 different test tubes to find the molecular weight of an unknown mixture. Tube 1 consists of pure Lauric acid, and Tube 2 consists of Lauric acid + an unknown solute mixture. From the calculations of this experiment, the molecular weight of the unknown acid can be found. A) How would the loss of some Lauric acid from Test Tube 1 have affected the calculation of a molecular weight? Would the calculated molecular...

From You have a mixture of benzoic acid, hexamethylenediamine, and 1-octanol dissolved in diethyl ether. You wish (for some reason) to separate these compounds and have pure samples of each. Devise a liquid-liquid extraction protocol that would allow you to do this. (up to 20 points) Your answer should be clear and concise. Ambiguous answers or those that are difficult to read will NOT receive points. Search entries or author Unread Subscribe Reply

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...
