REDOX TITRATIONS

Last Updated: 12th April 2024

  • Classes: 9

  • 77.95 Minutes
  • English

Redox titrations are a crucial analytical chemistry technique used to determine the concentration of a substance by measuring the transfer of electrons during a chemical reaction. In these titrations, a known concentration of a titrant is gradually added to a solution containing the analyte, leading to a redox (reduction-oxidation) reaction where electrons are exchanged. The endpoint, or equivalence point, is identified using indicators or other methods, indicating when the stoichiometrically equivalent amounts of analyte and titrant have reacted. This method finds extensive applications in fields like quality control, environmental analysis, and pharmaceutical research, thanks to its precision and adaptability in quantifying various substances in samples.

  • Explain the role of potassium permanganate (KMnO4) as an oxidizing agent in Redox titrations and its characteristic colo...
  • Calculate the molarity of analytes (e.g., Fe(II) ammonium tetraoxosulphate (VI) or sodium dioxonitrate (III)) using titr...
  • Describe the redox reaction between iodine and sodium thiosulfate (Na₂S₂O₃·5H₂O) in Redox titrations.
  • Calculate the molarity of iodine or other analytes based on titration results involving sodium thiosulfate.
