Titrimetric methods include powerful group of quantitative procedures that are based on measuring the amount of reagent consumed by the analyte. The volume or mass of the reagent needed to react completely with a fixed quantity of the analyte is obtained from which the amount of analyte is determined. Titration is based on a reaction between the analyte (unknown sample) and the regent of known concentration and reaction stoichiometry. TITRIMETRIC MTHODS Titrimetric methods are widely used in chemistry to determine oxidants, reductants, acids, bases, metal ions, etc.
