本文利用计算机绘制的综合平衡电位-总氯图研究了氯化亚铜在溶液中的平衡。作者首先通过实验和计算机拟合的办法对前人报导的不同的络合物稳定常数进行了精选,并采用了简单的活度系数计算公式,使计算与实测数据达到了偏差小于10％的吻合程度。在此基础上绘制的电位-总氯图对于两种不同方法还原含铜溶液制备氯化亚铜的工艺提供了有说服力的解释。研究说明这种计算及绘图方法不仅有益于实际体系的热力学分析,对于推算及评价有关的平衡常数也是有价值的。
In this paper, we calculated the equilibrium of cuprous chloride in solution by using the computer-made comprehensive equilibrium potential-total chloride diagram. The authors first selected different stability constants reported by previous authors through experiments and computer simulations, and adopted a simple calculation formula of activity coefficients to make the calculated and measured data less than 10% Anastomosis. Based on this, the potential-total chlorine diagram provides a convincing explanation for the two different methods of reducing copper-containing solutions to prepare cuprous chloride. The research shows that this method of calculation and drawing is not only beneficial to the thermodynamic analysis of the actual system, but also valuable for estimating and evaluating the equilibrium constants.
