ABSTRACT
Titrimetry or titrimetric analysis is any method of quantitative chemical analysis in which the amount of a substance is determined by measuring the volume that it occupies or the volume of a second substance that is needed to react completely with the substance being determined. The goal of titration is the equivalence point, where the addition of standard solution in an amount that is chemically equivalent to the substance with which it reacts. Most applications of precipitation titrations are based on the use of a standard silver nitrate solution and are therefore sometimes called argentometric methods. Compounds with two or more acidic or basic functional groups will yield multiple endpoints in a titration, provided the acidic or basic groups differ sufficiently in strength. Specific indicators owe their behavior to a reaction with one of the participants in the titration. In some complex-formation titrations, the endpoint is noted by the formation or disappearance of a solid phase.
