1 Exercise 0 TITRATION Theory: In chemistry a solution is a homogeneous mixture composed of two or more substances. In such a mixture:a solute is dissolved in another substance, known as a solvent.An aqueous solution is a solution in whitch the solvent is water. Concentration is the measure of how of a given substance (solute) there is mixed with
DETERMINATION OF CHLORIDE POTENTIOMETRIC METHOD .eusalt EuSalt/AS 016-2005 Page of 4 1. SCOPE AND FIELD OF APPLICATION The present EuSalt Analytical Standard describes a potentiometric method for the determination of chloride in sodium chloride. It is an application of the ISO 6227 Standard (1) to sodium chloride. 2. REFERENCES
Precipitation Titration: Determination of Chloride by the Mohr Method by Dr. Deniz Korkmaz Introduction Titration is a process by which the concentration of an unknown substance in solution is determined by adding measured amounts of a standard solution that reacts with the unknown.
End point detection precipitation titration : 1) formation of a second colored precipitate (Mohr method): This method depends on formation of second highly colored precipitate for detect end point. This method has been widely applied to the titration of chloride ion and bromide ion with silver nitrate, and the indicator is chromate ion (CrO4-2)
Titrimetric Analysis: Methods . Precipitation Titrations Precipitation reactions in aqueous solution range from rapid to slow, depending on the identity of the precipitant. Many precipitations are sufficiently rapid and complete to form the basis of quantitation . termed argentometric titrations. Sodium chloride is suitable as a primary .

In volumetric titrations, the volume of the titrant solution is used to calculate nT.By simple dimensional analysis, nT = mol T vol soln! vol added soln =CT!VT where CT is the concentration of the titrant solution in M, and VT is the volume of titrant solution needed to reach the equivalence point.
Determination of Chloride Ion Concentration by Titration (Mohr's Method) Introduction This method determines the chloride ion concentration of a solution by titration with silver nitrate. As the silver nitrate solution is slowly added, a precipitate of silver chloride forms. Ag+ (aq) + Cl– (aq) → AgCl (s) The end point of the titration .
