WebAug 12, 2024 · The Volhard method is a type of precipitation titration and an example of back titration, first described by a German chemist, Jacob Volhard in 1874. It is used to determine the halide concentration using a back titration, which involves titrating chloride solution with silver ions and then determining the excess silver ion content in the ... WebDec 21, 2024 · Procedure of Volhard titration method: Procedure for determination of chloride ion concentration by titration (Volhard’s Method) Fill the burette with 0.1 M potassium thiocyanate solution and adjust the zero. Measure 100 ml of the sample and pour it into a conical flask. Add 01.00 ml of ferric ammonium sulphate solution as an indicator.

WebA solution containing chloride ion was analyzed by the Volhard method. A 50.00 mL sample containing chloride ion was treated with 25.00 mL of 0.2500 M silver nitrate. The precipitated AgCl was removed from the solution by filtration, and 1.00 mL of 0.1000 M Fe3+ was added to the filtrate. This new solution was then titrated with 10.67 mL of 0. ... WebMar 31, 2006 · The aim of this paper is to compare the performance parameters of the Volhard method for chlorides determination obtained applying the bottom-up approach with those experimentally achieved. The method precision, trueness, detection and quantification limits and ruggedness are determined analysing various foods with different chloride … react hook redux

WebIn an attempt to secure a convenient, rapid, and accurate method of determining the chloride content of blood plasma, the following application of the Volhard principle was found to be satisfactory. This principle is the precipitation of the chlorides by a standard solution of silver nitrate and the subsequent ti- tration of the excess silver ... WebAbstract. Three samples of ground Gouda cheese containing 1-2% chloride were analyzed by 7 laboratories by 3 methods: oxidation with KMnO4 and HNO3 followed by a Volhard titration; the same but with filtering off the precipitated AgC1 before back-titration; and the general potentiometric method without ashing or oxidation.
