Standardredukt
Standardredukt is a term used in analytical chemistry and electrochemistry to denote a defined reducing agent with a well-characterized reducing capacity under standardized conditions. It functions as a reference reagent for calibrating redox measurements, driving controlled redox reactions, and enabling quantitative assessments of oxidizers.
Definition and conditions: A Standardredukt is specified by its standard reduction potential E°(Red/Ox) under defined conditions,
Properties and selection: Standardredukte are selected for known stoichiometry, chemical stability, and compatibility with the solvent
Applications: In redox titrations, the Standardredukt provides a known amount of reducing equivalents to determine the
Examples: In aqueous systems, common Standardredukte include ascorbate, sulfite, and certain hydrazine derivatives under appropriate conditions.
