Web2 aug. 2024 · “Indirect titration ” means that analyte A is converted chemically before titration and is not titrated on its own. An exact volume of the sample is measured and submitted to the titration flask. An accurately measured volume of a solution of substance B, with which analyte A forms the stoichiometric reaction product A x B y , is also given … WebIn direct titration, the sample dissolves in the titration vessel before the titration starts. For some samples that dissolve slowly in the solvent, an extended stirring time is necessary. Internal extraction is performed in a specific heated cell at 50 °C for samples that are not soluble and release water slowly.
Web19 mei 2024 · This indirect alkalimetric titration is also commonly called back titration. Back titration is generally used because of the slow reaction between the titrant and the titrate solution, the instability of the titrate solution under study, or indicators that say that direct titration is not suitable. WebIndirect titration is also known as Back Titration. The next category of titrations is based on the nature of solvents and the nature of the chemical reaction. This category includes …
