本文利用文献[1]的结果计算了碳酸在水溶液中的真实电离常数，分别为5、15、25、35、38和45。在相同温度下的高场电导测量。与表观电离常数相比，真电离常数随温度的变化很小，本文用高场电导数据计算了碳酸在25 ℃时的真电离常数。[2]与25岁时的结果相比，唯一可用的其他数据是劳顿的数据。3.为了检验高场电导测量数据的一致性，并与表观电离常数随温度的变化进行比较，将高场电导测量扩展到温度5、15、25、35、38和45，以及碳酸的真实电离常数（方程式1）。3，参考文献2）已在这些温度下计算。正如Roughton所指出的，鉴于反应的重要作用，
The true ionization constant of carbonic acid in aqueous solution has been determined at 5, 15, 25, 35, 38 and 45 through calculations utilizing the results of. high field conductance measurements at the same temperatures. The true ionization constants, in contrast with the apparent ionization constants, change but little with change in temperature.The true ionization constant of carbonic acid at 25 has been computed from high field conduct-ance data in a previous paper. 2 The only other data available for comparison with this result at 25 were those of Roughton. 3 In order to obtain a check on the consistency of the data derived from high field conductance measurements and to af-ford a comparison with the variation of the apparent ionization constant with temperature, the high field conductance measurements havebeen ex-tended to include the temperatures 5, 15, 25, 35, 38 and 45, and the true ionization constant of carbonic acid (eq. 3, ref. 2) has been calculated at these temperatures. As Roughton3 has pointed out, in view of the important role of the reactions
