When the titrand contains read more an analyte and an interferent, then selectivity is dependent upon their relative acid strengths. Two limiting predicaments has to be deemed.

In the 2nd limiting circumstance the analyte is actually a weaker acid compared to the interferent. In this instance the amount of titrant required to reach the analyte’s equivalence place is determined via the focus of each the analyte and the interferent. To account for that interferent’s contribution to the top position, an end level to the interferent need to be existing.

To judge the relationship involving a titration’s equivalence stage and its conclusion place, we have to build only an inexpensive approximation of the precise titration curve. In this particular section we exhibit an easy approach for more info sketching an acid–base titration curve.
