What is the difference between endpoint and equivalence point titration?
Endpoint titration mode (EP): The endpoint mode represents the classical titration procedure: the titrant is added until the end of the reaction is observed, e.g., by a colour change of an indicator. With an automatic titrator, the sample is titrated until a predefined value is reached, e.g. pH = 8.2. Equivalence point titration mode (EQP): The equivalence point is the point at which the analyte and the reagent are present in exactly the same concentration. In most cases it is virtually identical to the inflection point of the titration curve, e.g. titration curves obtained from acid/base titrations. The inflection point of the curve is defined by the corresponding pH or potential (mV) value and titrant consumption (mL). The equivalence point is calculated from the consumption of titrant of known concentration. The product of concentration and the titrant consumption gives the amount of substance which has reacted with the sample. In an autotitrator the measured points are evaluated ac
