Introduction Potentiometric titration is an analytical method that determines the concentration of an analyte by measuring the electrode potential during titration. Unlike color-based indicators in conventional titrations, potentiometric titrations use electrodes to detect the endpoint without requiring visual indicators. Methods to Determine the End Point of Potentiometric Titration The endpoint of a potentiometric titration is […]
1. Introduction to Iodometry Iodometry is a type of volumetric analysis that involves the determination of an oxidizing agent by titrating it with a standard solution of sodium thiosulfate (Na₂S₂O₃). In an iodometric titration, iodine (I₂) is generated in situ by the reaction between an oxidizing agent and excess iodide ions. The iodine is then […]
A redox indicator is a chemical compound that changes color at a specific oxidation-reduction (redox) potential. These indicators are widely used in redox titrations to signal the endpoint of a reaction. Common Examples of Redox Indicators are Ferroin, Methylene Blue, Diphenylamine, and Starch-Iodine Complex. Characteristics of Redox Indicators: Types of Redox Indicators Redox indicators are […]
Redox titrations are a fundamental aspect of volumetric analysis, wherein a solution of known concentration (titrant) reacts with a solution of unknown concentration (analyte) through oxidation and reduction (redox) reactions. These titrations are pivotal in determining the concentration of reducing or oxidizing agents and are widely used in chemical, pharmaceutical, and industrial applications. or Redox […]
