Chem 1211L Mrs. Amy Cook February‚ 9 2011 Lab report on separation of mixtures Purpose- The purpose of this lab is to separate or isolate the desired product from large amounts of solvent and by-products. It is also followed by a purification step that removes trace amounts of other substances from the final product. One of the experimental techniques that we used in the lab to separate or purify mixture is fractional crystallization. In the experiment we used fractional crystallization to resolve

Testing the pH of Common Household Substances Lab Background Information: The pH scale is used to determine the acidity or basicity level of liquid solutions. If a solution scores a pH level of 1-6 it is an acidic solution‚ 1 being the most acidic and 6 being the least acidic. If a solution rates a pH level of 7 it is a neutral solution‚ meaning it is neither an acidic nor a basic solution. Lastly‚ if a solution is 8-14 on the pH scale it is a basic solution‚ 8 being the least basic and 14 being

Introduction: Recrystallization is used for the purification of solid compounds. The recrystallization process relies on the fact that majority of compounds are more soluble in hot solvent than in cold. The hot saturated solution containing the compound will have unwanted impurities and will be filtered out and cooled to produce the pure crystal constituents of the compound. Thin layer chromatography can be used as a physical method to segregate compounds from natural sources. E.g. Spinach
