WebQ8. Explain the Volhard method and the Fajan method of precipitation titration. Answer. The Volhard method is a type of precipitation titration that is used to determine the bromine, chlorine, and iodine content of a halide by precipitating it with excess silver nitrate and titrating the excess by adding standard potassium thiocyanate (KSCN). Web2. The Determination of Chloride by the Mohr Method Discussion The Mohr method uses chromate ion as an indicator in the titration of chloride ion with silver nitrate. The first excess of titrant results in the formation of a red silver chromate precipitate, which signals the end point. INDICATOR Sodium chromate, 5% Indicator PROCEDURE
