1/15
  • Oxidation State
    A numerical value representing the charge an atom would have if all bonds were ionic, crucial for redox analysis.
  • Redox Titration
    A quantitative analysis method where electron transfer reactions determine analyte concentration.
  • Analyte
    The substance in a chemical analysis whose composition or concentration is being measured.
  • Oxidizing Agent
    A chemical species that accepts electrons, causing another species to increase its oxidation state.
  • Reducing Agent
    A substance that donates electrons, causing another species to decrease its oxidation state.
  • Cerium(IV) Ion
    A powerful oxidizer, often used to convert iron(II) to iron(III) by accepting electrons.
  • Peroxydisulfate
    A strong oxidizer, especially effective with a silver catalyst, capable of oxidizing even cerium(III).
  • Jones Reductor
    A reduction column filled with zinc amalgam, used to reduce analytes to a single oxidation state.
  • Walden Reductor
    A reduction column containing silver granules, used to reduce analytes in acidified solutions.
  • Hydrogen Peroxide
    A versatile reagent acting as either an oxidizer or reducer, depending on the solution's acidity or basicity.
  • Auxiliary Reducing Agent
    A metal or compound used to ensure the analyte is fully reduced to a single oxidation state before titration.
  • Auxiliary Oxidizing Agent
    A reagent used to convert all analyte species to a higher oxidation state, ensuring uniformity for titration.
  • Reduction Column
    A device packed with a reducing metal, facilitating the conversion of analytes to a single oxidation state.
  • Pre-oxidation Stage
    A preparatory step where analytes are oxidized to a uniform state before quantitative analysis.
  • Pre-reduction Step
    A preparatory process where analytes are reduced to a single oxidation state prior to titration.
