要善于分析水在常见反应中的作用湖南祁东三中（４２１６６１）李德和水是一种常见的溶剂，许多化学反应是在水溶液中进行的．用化学方程式表示其反应，可看出反应物和生成物各是什么物质，但没有反映出变化过程，下面以水在常见化学反应中的作用为例，分析一些具体问题．...
To be good at analyzing the role of water in common reactions Hunan Mindong Sanzhong (421661) Li Dehe water is a common solvent, many chemical reactions are carried out in aqueous solution. The chemical equation is used to express the reaction. It can be seen that the reactants and the products are all substances, but they do not reflect the change process. The following takes the role of water in common chemical reactions as an example to analyze some specific problems. ...
