物理化学中的电化学知识告诉我们,电对的电极电势数值越大,其氧化态的氧化性越强;电对的电极电势的数值越小,其还原态的还原性越强。可逆电极的电极电势为:φ=φ°-+ＲＴｎＦｌｎａ氧化态ａ还原态其中φ°-为电极的标准电极电势,ａ氧化态为电对氧化态的活度,ａ还原态为电对还原 The electrochemical knowledge in physical chemistry tells us that the larger the electrode potential value of the pair, the stronger the oxidation of the oxidation state; the smaller the value of the electrode potential of the pair, the stronger the reduction of the reduced state. The electrode potential of the reversible electrode is: φ=φ°−+RTnFlna oxidation state a reduced state where φ°− is the standard electrode potential of the electrode, a oxidation state is the activity of the electro-oxidation state, and a reduction state is the electro-pair reduction
