本文研究了在环境条件下，自由CO_2浓度从接近饱和浓度变化到平衡浓度的CO_2 + H_2O体系。离子组分浓度对溶液pH值的依赖性被确定。同时测定了溶液的电导率和pH值，结果表明：碳酸盐-水体系中离子组分对溶液电导率的贡献是加和的，满足Kohlrausch定律，误差不超过± 0.5%。
The system CO2 + H2O with the concentration of free carbon dioxide varying from those close to the saturation one to the equilibrium one under environmental conditions has been studied. The dependences of ionic component concentrations on the solution pH are determined. Simultaneous measurements of the electric conductivity and the pH of the solution show that the contributions of ionic components in the carbonate-water system to the electric conductivity of the solution are additive and satisfy the Kohlrausch law with an error not exceeding ±0.5%.
