Indicators & Acid–Base Titrations Inquiry Guidance & AP* Chem Curriculum Alignment Transition Guide


Acids and bases vary in their strength and are normally classified as strong or weak. In any acid–base titration, the neutralization, or equivalence point, occurs when the moles of acid in solution are equal to the moles of base. The pH of the solution at this point will vary widely and depends on the strength of both the acid and the base. How is an indicator selected that fits a particular acid–base titration?
