Which point on the titration curve represents complete neutralization of the analyte?

• A. Equivalence Point
• B. Endpoint
• C. Midpoint
• D. Anchor Point

Answer: (A)

In a titration, complete neutralization occurs at the equivalence point—the moment when the amount of titrant added equals the amount of analyte present in a stoichiometric ratio, so all of the analyte has reacted. On the titration curve this shows up as the inflection point or steepest part, where pH changes most rapidly with small additions of titrant. The endpoint, the observable color change of an indicator, should align with this point but can be offset depending on the indicator’s pH range. The midpoint is when only half the analyte has been neutralized (pH equals the acid’s pKa for a weak acid), not when neutralization is complete. The term anchor point isn’t a standard part of this concept.
