目前在大中学校,无机化学课程中常用下面两个反应分别来验证浓度和温度对化学平衡移动的影响:这种传统的实验方法存在下面一些缺点:对于(1)式中加固体KCl使红色变浅解释为生成物浓度的增加使平衡左移,事实上加其它任何强电解质后都可以使上述平衡向左移动。这个问题早已为实验所证实,并有不少文章指出过。另外,把浓度对平衡的影响与温度对平衡的 At present, the following two reactions are commonly used to verify the effects of concentration and temperature on the chemical equilibrium shift in large and medium-sized schools and inorganic chemistry courses: The traditional experimental method has the following disadvantages: For the (1) The shallow explanation is that the increase in the concentration of the product shifts the balance to the left, in fact, adding any other strong electrolyte can shift the equilibrium to the left. This problem has long been confirmed by experiments, and many articles have pointed out. In addition, the impact of concentration on the balance and temperature on the balance
