化学平衡理论在中学化学中有着举足轻重的地位,是研究可逆反应、弱电解质电离、盐类水解等问题的工具性知识,由于其内容比较抽象,对学生的思维能力要求较高,一直是中学教学的难点之一。笔者设计了一组模拟实验,将抽象的化学平衡知识具体化,增强了学生对化学平衡的感性认识,取得了很好的效果。一、实验用品水槽两只、大烧杯三只、水、红墨水。二、实验步骤1.将水加入一只烧杯和一只水槽中至其容积的2/3 Chemical equilibrium theory plays an important role in chemistry in middle schools. It is a tool for studying reversible reactions, weak electrolyte ionization, salt hydrolysis and other issues. Because of its relatively abstract content and high requirements on students’ thinking abilities, One of the difficulties. The author designed a set of simulation experiments that embodied the abstract knowledge of chemical equilibrium and enhanced students’ perception of chemical equilibrium and achieved good results. First, experimental supplies sink two, three large beakers, water, red ink. Second, the experimental steps 1. Add water to a beaker and a sink to its volume 2/3
