Together with gravimetry,titration is one of the oldest analytical techniques,and both belong to a group of analytical methods that are based on chemical reaction

摘要

In titration one determines the volume of a standard solution (titrant) that is necessary for complete chemical reaction with the analyte.The titrant contains a known- amount of a particular substance.Since,Loschmidt and Avogadro we know that one gram molecule of a substance contains a defined number of particles.
