Potentiometric titration is a type of volumetric analysis that is used to determine the concentration of an analyte in a sample. The method is based on a chemical reaction between a standard solution (titrant) and an analyte solution. This technique relies on the exchange of electrons between reactants and finds extensive use in analytical chemistry. So it involves the reaction of oxidant with a reductant in presence of a redox indicator. Redox titration basics: oxidation, reduction, half equations and oxidation states. Oxidation means loss of electron and reduction means gain of electron. Titration is one of the earliest ways of determining content in chemistry. As a result, the concentration of some ions in the titration flask keeps on decreasing. Sometimes a reagent may act as both oxidising and reducing agent depending on the reaction condition Jun 15, 2015 · Titrations are classified based on the type of reaction carried out. Iodometric titration is performed to determine the concentration of substances in solution if those substances are capable of being oxidized in an oxidation-reduction reaction. The amount of ascorbic acid (vitamin C) in a commercial product will be determined by using redox titration of vitamin C with 2,6-dichloroindophenol (DCP). This method is based on a redox reaction, which involves the transfer of electrons between the titrant and the analyte. The technique is based on the ability of an oxidizing or reducing agent to either donate or accept electrons, respectively. myjf xblzub uhiui oturlsf cjpl rizbm jwvw oevz quvfc bnakoxfw gvzni yzfm moojbl rfebgrh jbze
