- Definition derjenige Punkt bei einer Titration, bei dem sich eine ausgewählte Eigenschaft der Lösung (z. B. die ihr durch einen Indikator verliehene Farbe ...) deutlich ändert Reference "Thieme RÖMPP Online, Eintrag zu ""Endpunkt"", Thieme, 2010, https://roempp.thieme.de/roempp4.0/do/data/RD-05-01085 (20.7.2017)"
- Comment "Der Endpunkt liegt mehr oder weniger direkt am Äquivalenzpunkt (theoretischer Endpunkt). Bei der graphischen Methode der Bestimmung des Endpunktes wird dieser als Schnittpunkt von zwei Geraden oder Kurven erhalten.Quelle: Thieme RÖMPP Online, Eintrag zu ""Endpunkt"", Thieme, 2010, https://roempp.thieme.de/roempp4.0/do/data/RD-05-01085 (20.7.2017).Siehe auch: - Äquivalenzpunkt [ IATE:1581531 ]- Titration [ IATE:1594555 ]"

- Definition the point in the titration once the equivalence point has been reached, indicated by some form of indicator which varies depending on the type of titration being done Reference "UC Davis, Titration Fundamentals, http://chemwiki.ucdavis.edu/Analytical_Chemistry/Quantitative_Analysis/Titration/Titration_Fundamentals [20.11.2015]"
- Comment "If a color indicator is used, the solution will change color when the titration is at its end point.The endpoint of a titration is NOT the same thing as the equivalence point. The equivalence point is a single point defined by the reaction stoichiometry as the point at which the base (or acid) added exactly neutralizes the acid (or base) being titrated. The endpoint is defined by the choice of indicator as the point at which the colour changes. Depending on how quickly the colour changes, the endpoint can occur almost instantaneously or be quite wide. If an appropriate indicator is chosen such that the endpoint of the titration occurs at the equivalence point, then a colour change in the solution being titrated can be used as a signal that the equivalence point has been reached. The volume of titrant needed to reach the equivalence point can then be read, allowing us to calculate concentrations, volumes, Ka's etc.See also:- equivalence point [ IATE:1581531 ]- titration [ IATE:1594555 ]"
