Question:
In an acid/base titration, why must the indicator (phenolphthalein) be a strong dye?
Titrations:
In a titration, the goal is to determine the concentration of an unknown acid or base solution by slowly adding a base / acid with known concentration. An indicator is used to let us know when the equivalence point is reached.
