Abstract Starting from the oxidizing properties comparison between concentrated nitric acid and dilute nitric acid in the college entrance examination questions, this paper expounded the fallacy of the current oxidizing property comparison. Starting from the concept of oxidability, taking the oxidability of nitric acid as an example, the evidence of oxidation strength comparison was sought from three aspects: structure, property and electrode potential. Through the comparison of the oxidizing strength of the same substance by changing conditions (concentration, pH, etc.), the idea of oxidation (reduction) properties comparison and its influence on redox reaction were explored from qualitative to quantitative.
