Aug 29, 2023 · The standard reduction potentials in Table \(\PageIndex{1}\) can be interpreted as a ranking of substances according to their oxidizing and reducing power. Strong oxidizing agents are typically compounds with elements in high oxidation states or with high electronegativity, which gain electrons in the redox reaction (Figure \(\PageIndex{1}\)). Reduction potentials can be positive or negative. Reduction potential tells you the E value for reduction. If you want the E for oxidation, it is the opposite of the E for reduction (Ex: E reduction = +33 , E oxidation = -33). A more positive E value for the half reactions = more likely to get reduced (gain electrons)
