Explanation:
Phenolphthalein drops should be used in a solution rather than directly on soap, and can only tell you so much. The main issue with phenolphthalein drops is how they work as a pH indicator. When added to a solution, phenolphthalein changes from clear to pink, depending on the pH of the solution.
