[交流] 【求助】浓酸的氢离子浓度怎么表示已有1人参与

浓酸的氢离子浓度怎么表示？比如说(54% P2O5)的浓磷酸，8M的硫酸，对这些浓酸怎么比较他们氢离子浓度的大小？我在一篇文献中看到用R0(H)来表示，但是没搞懂，
The ferrocene/ferricinium pair (Fc+/Fc)was taken as the redox indicator and the quinone/hydroquinone pair(Q/H2Q) as the pH indicator. R0(H) was determined using simple potentiometric measurements, taking the system (Fc+/Fc)as the comparison. R0(H) acidity is related to measurements of potential by the following equation [3]:R0(H) =( E H2O (Q/H2Q) − E H2O−acid (Q/H2Q))/0.058
where E H2O (Q/H2Q) represents the potential of the system (Q/H2Q) measured in water and E H2O−acid (Q/H2Q) represents the potential of the system (Q/H2Q) measured in the phosphoric acid solution. These potentials are expressed in relation to the system Fc+/Fc.
哪位大侠能告诉我怎么对浓酸的氢离子浓度进行表示，并能够通过测量对它们之间进行比较？
