Experiment: Identification of Unknowns* Introduction
classes.kvcc.edu5 | P a g e In this experiment, carboxylic acids (pKa~5) are generally indicated when a compound is soluble in both bases, while phenols (pKa~10) are indicated when it is soluble in NaOH only. Compounds dissolve in base because they form sodium salts that are soluble in the aqueous medium.
