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.
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.
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.
20 Ιουν 2023 · A titration is a volumetric technique in which a solution of one reactant (the titrant) is added to a solution of a second reactant (the "analyte") until the equivalence point is reached. 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 ...
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.
For most acid–base titrations the inflection point—the point on a titration curve that has the greatest slope—very nearly coincides with the titration’s equivalence point. The red arrows in Figure 6.6.4 , for example, identify the equivalence points for the titration curves in Example 6.6.1 .
In this tutorial, you will learn about titration curves, titration analysis and the steps required to perform one. You will also learn about equivalence points and endpoints, and titration calculations.
