The comparison of dehydration of maleic acid and fumaric acid to yield maleic anhydride is to be explained. Concept introduction: The reaction between carboxylic acids and acyl chloride in the presence of pyridine gives carboxylic anhydrides. This occurs due to the deprotonation of carboxylic acid by pyridine. There is another form of anhydride called cyclic anhydride, which can be prepared simply by heating the carboxylic acids at a certain temperature.

Question

How would you prepare 1 liter of a 50 mM Phosphate buffer at pH 7.5 beginning with K3PO4 and 1 M HCl or 1 M NaOH? Please help and show calculations. Thank you

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
