仿照前文,选定汞齐中钾的标准态并规定钾汞齐的标准电极电位。本文利用前人数据,采用一般化学热力学方法计算在25°钾汞齐的标准电极电位ε°的数值,并以图表示该温度下不同浓度的钾汞齐与不同浓度的氢氧化钾溶液的平衡电位ε的数值。 Armbruster等、Bent等和柴田荣一等曾用电动势法测定汞齐中钾的活度。本文由Armbruster等的结果(原文得出的是汞齐中汞的活度系数a_1/N_1),用Gibbs—Duhem
Following the previous article, the standard state of potassium in the amalgam is selected and the standard electrode potential of potassium amalgam is specified. In this paper, we use the general chemical thermodynamics method to calculate the standard electrode potential ε ° at 25 ° potassium amalgam using the previous data and graphically show the equilibrium of different concentrations of potassium amalgam at different temperatures with different concentrations of potassium hydroxide solution The value of the potential ε. Armbruster et al., Bent et al., And Shibata Shibata et al. Used electrokinetic methods to determine the activity of potassium in amalgams. In this paper, the results of Armbruster et al. (The original results for the activity coefficient of amalgam in amalgam, a_1 / N_1) were calculated using Gibbs-Duhem
