This titration has widespread uses in the areas of agriculture, food, pathology and water analysis. Silver nitrate is available in AR grade form, but it is hygroscopic and therefore unable to be used as a primary standard. It can be standardised against dried sodium chloride.
TITRIMETRIC ANALYSIS OF CHLORIDE. Introduction. The purpose of this experiment is to compare two titrimetric methods for the analysis of chloride in a water-soluble solid. The two methods are: • a weight titration method using a chemical indicator; • a volumetric titration method using potentiometric detection.
In chloride solution, due to excess of chloride ions, they form the primary layer of the precipitate. The second layer is formed by the cations of sodium. The reaction ends with the silver ion in excess.
Concentration of Sodium chloride is calculated from titration volume of Silver nitrate. 1) When the test sample contains a small amount of chlorine, it is necessary to titrate in alcoholic solvent not aqueous solvent to raise sensitivity of electrode.
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 (1) INTERNATIONAL STANDARD ISO 6227.

containing chloride ions, forming a precipitate of silver chloride. The term 'excess' is used as the moles of silver nitrate added are known to exceed the moles of sodium chloride present in the sample so that all the chloride ions present will react. Ag+ (aq) + Cl– (aq) → AgCl (s) The indicator Fe3+ (ferric ion) is then added and the
In this experiment, the amount of chloride in an unknown sample was determined by Mohr titration. The titration was carried out at a pH between 7 and 10 because chromate ion is the conjugate base of the weak chromic acid (2, 3). Therefore, when the pH is lower than 7, chromate ion is protonated and the chromic acid form predominates in the solution.
