Resumen de Dissolving Carboxylic Acids and Primary Amines on the Overhead Projector

Sally D. Solomon, Susan A. Rutkowsky

• Liquid carboxylic acids (or primary amines) with limited solubility in water are dissolved by addition of aqueous sodium hydroxide (or hydrochloric acid) on the stage of an overhead projector using simple glassware and very small quantities of chemicals. This effective and colorful demonstration can be used to accompany discussions of the properties of carboxylic acids and amines in general chemistry as well as organic chemistry.
