在生产、生活及化学研究中,人们常需要根据不同原子、分子或离子的某些特征反应,对物质进行检验,以确定物质的组成.但是有些同学往往考虑问题不全面或选择的实验方法不恰当,造成试剂的浪费或者得出错误结论。下面就检验中常见问题作一些简单的分析. In production, life, and chemical research, people often need to test substances to determine the composition of substances based on certain characteristics of different atoms, molecules, or ions. However, some students often consider that the problem is not comprehensive or the selected experimental method is not Properly, it wastes reagents or leads to wrong conclusions. Here are some simple analysis of common problems in inspection.
