Question

when performing a titration with phenolphthalein dye what color change occurs as the pH increases from 8 to 11?

Answer 1

A strong acid- strong base titration is performed using a phenolphthalein indicator. Phenolphthalein is chosen because it changes color in a pH range between 8.3 – 10. It will appear pink in basic solutions and clear in acidic solutions.
