WebSubstances such as phenolphthalein, which can be used to determine the pH of a solution, are called acid-base indicators. Acid-base indicators are either weak organic acids or … WebAug 20, 2014 · Phenolphtalein is slightly acidic. It does affect titration because if you add too much, then it will alter the concentration of whichever solution you are adding it in. If you added it to the acid, it will cause that acid to be more acidic than you may have calculated.
