一、前言在溶液中发生的包含有多种平衡的化学反应,是由两个或两个以上简单反应组合而成的反应。即复杂反应,这类反应能否进行?进行到什么程度?弄清楚这些问题,对于了解溶液平衡是非常必要的。本文试图采用常规的近似处理,定量地说明问题,虽然结果不很精确(忽略了许多影响因素)但与实验结果基本相符。对复杂反应能否进行,物质能否溶 I. INTRODUCTION A chemical reaction involving multiple equilibria that takes place in solution is a combination of two or more simple reactions. That is, complex reactions, such reactions can proceed? To what extent? Clear understanding of these issues, for understanding the solution balance is necessary. This paper attempts to use conventional approximation to quantify the problem. Although the result is not very accurate (ignoring many influential factors), it basically agrees with the experimental results. Whether the complex reaction can be carried out, the material can dissolve
