The term "equivalence point" means that the solutions have been mixed in exactly the right proportions according to the equation. The term "end point" is where the indicator changes colour. As you will see on the page about indicators, that isn't necessarily exactly the same as the equivalence point.

The equivalence point, or stoichiometric point, of a chemical reaction is the point at which chemically equivalent quantities of reactants have been mixed. For an acid-base reaction the equivalence point is where the moles of acid and the moles of base would neutralize each other according to the chemical reaction.
We begin by calculating the titration’s equivalence point volume, which, as we determined earlier, is 25.0 mL. Next we draw our axes, placing pH on the y-axis and the titrant’s volume on the x-axis. To indicate the equivalence point volume, we draw a vertical line corresponding to 25.0 mL of NaOH.
Equivalence point is represented as the midpoint of the vertical section of the titration curve. Calculation: Endpoint is used to calculate the volume of titrant required to reach the equivalence point. Equivalence point is used to calculate the concentration of the analyte.
7 Οκτ 2019 · The equivalence point of a chemical reaction is the point at which equal quantities of reactants are mixed chemically. In other words, while titrating, it is a point where the amount of added titrant is enough to neutralize the analyte solution completely.
20 Ιουν 2023 · The equivalence point is the point at which titrant has been added in exactly the right quantity to react stoichiometrically with the analyten (when moles of titrant = moles of analyte). If either the titrant or analyte is colored, the equivalence point is evident from the disappearance of color as the reactants are consumed.
14 Αυγ 2020 · The equivalence point of an acid–base titration is the point at which exactly enough acid or base has been added to react completely with the other component. The equivalence point in the titration of a strong acid or a strong base occurs at pH 7.0.
