The 2-naphthol should also have impurities because the strong base (hydroxide) would remove all of the leftover benzoic acid along with the 2-naphthol from the organic phase the reactions for the extractions were as follows. Standardization chemistry lab report standardization chemistry lab report 1657 words jul 13th, 2011 7 pages this is a chemistry lab report on an acid-base titration experiment 2714 words | 11 pages essay about organic chemistry ii lab report. The reaction differentiated between the two organic acids based on their difference in pka the bicarbonate solution extracted the stronger base because the reaction was favored with benzoic acid, but the base was not strong enough to extract the 2-naphthol all solids extracted were allowed to air dry in the lab locker for one week, then.
A mixture of an organic acid, base, and neutral compound can be separated into its three base components using a three-part acid-base extraction first the acid is extracted by adding an inorganic base which reacts with the acid to form a salt. Experiment 1 title: acid-based extraction objective: to learn the concept of separating organic compounds by utilizing the concept of acid/base chemistry in so that separation can be done.
Via and acid/base reaction the changes in charge and polarity upon reaction for these species can be used to separate them due to their changes in solubility the general flowchart of the separation is shown below. Experiment #4: acid/base extraction acid/base is an extremely useful separation technique in organic chemistry using simple acid/base reactions, several different classes of organic molecules can be separated from one another this procedure is most easily visualized using the flow chart for acid/base extraction on.

Chemistry 52 1 acid and base strength indicators are organic compounds that change color in a specific way, depending on the acidic or basic nature of the solution a wide variety of indicators are commonly used in the chemistry laboratory, to identify the acidic or basic nature of an aqueous solution this experiment uses. About this lab report i can distinguish the color of the acids and bases with a ph indicator, and i can note that the bases and acids commonly are around us but we don't notice that, until we know about the topic, i can learn that some things that we use in our daily life are acid, bases or neutrals, and that even sometimes it shows like it was.
