Standard reduction potentials quantify the thermodynamic tendency of chemical species to acquire electrons and thus directly dictate the oxidizing and reducing strengths of redox couples.
The claim states a foundational principle of electrochemistry and thermodynamics (standard reduction potentials quantify oxidizing and reducing agent strength), which is a matter of textbook definition and common knowledge in chemistry. None of the retrieved papers specifically contest this fundamental thermodynamic law; rather, they apply or compute redox potentials in various specialized contexts. Therefore, the statement is classified as common knowledge requiring no citation.
