Question

The chemical phenolphthalein can be clear or pink depending on the pH of the solution. Which role would phenolphthalein most likely play in an acid-base titration?(1 point) Responses analyte analyte indicator indicator salt salt titrant

Answer 1

Phenolphthalein would most likely play the role of an **indicator** in an acid-base titration. It is used to signal the end point of the titration by changing color (from clear to pink) as the pH of the solution changes.
