QUESTION 9 Acid-Base Titration In this experiment, an indicator called phenolphthalein is used to signal the endpoint of the titration (when the acid has been fully neutralized by the base). The indicator is colorless in acidic solution and pink in basic solution. During the titration, the pink color will appear and then disappear quickly with each addition of base (titrant). If a student is having trouble seeing the pink color in the sample flask, what can be done to help them see the color more clearly? Experiment - Acid-Base Titration.pdf O Remove safety goggles to get them out of the way. O Add several more drops of indicator - the more the better! O Place a piece of white paper or a white paper towel beneath the sample flask. O Place something dark beneath the sample flask.
