Q: Hydrogen peroxide assay is performed by:
  • A. Diazotisation titration
  • B. Non-aqeous titration
  • C. Neutralisation titration
  • D. Redox titration
Correct Answer: Option D - Hydrogen peroxide assay is performed by redox titration. Hydrogen peroxide in a diluted portion of the sample is quantitatively oxidized by titration with a potassium per magnate (KMnO4) solution of known strength. Compounds that are oxidized by KMnO₄ under acidic conditions interfere.
D. Hydrogen peroxide assay is performed by redox titration. Hydrogen peroxide in a diluted portion of the sample is quantitatively oxidized by titration with a potassium per magnate (KMnO4) solution of known strength. Compounds that are oxidized by KMnO₄ under acidic conditions interfere.
