In the organic chemistry lab course there are two types of reports, which are all graded on a 100 point scale One type comprises what's commonly known as "lab reports," that is, records referring to experiments performed in the lab The other type refers to special assignments that are completed outside the laboratoryIn organic chem, there are different types of experiments technique and preparative A technique experiment is one in which you are performing a technique for the first time and studying its details, for example, distillation and extraction A preparative experiment is one in which a compound is synthesized from other reagents Physical DataAn organic solvent to dissolve a neutral organic compound to separate it away from inorganic, aqueous soluble "trash" In today's lab, we are adding a base to form an ionic salt from the organic compound, which will make it water soluble to separate it from the compound(s) still soluble in the ether solvent 2

Experiment 6 Esterification Of An Unknown Alcohol And Carboxylic Acid
Chemistry Lab Report Percentage Recovery of the Benzil and Benzoic Acid by Macro Extraction Technique Vanmala Sharma Introduction The purpose of this lab was to separate two organic compounds, Benzil and Benzoic acid, based on their difference in solubility in different solvents, by extraction technique; The most important point to keep in mind throughout the entire extraction process is which layer contains the product For an organic compound, it is relatively safe to assume that it will dissolve better in the organic layer than in most aqueous solutions unless it has been converted to an ionic specie, which makes it more watersolubleIntroduction The purpose of this experiment was to conduct an acidbase extraction on an organic acid, base and neutral organic molecules This was conceptually possible due to the solubility properties of the salt in organic acids and bases which allows organic solvents to dissolve into an aqueous layer from an organic layer ("25 Solubility, Melting Points and Boiling Points")
