所谓微型化学实验,就是以尽可能少的化学试剂来获取所需化学信息的实验方法与技术,它具备两个突出的特点:微型化学实验中所需药品用量较少;在微型化的仪器装置中进行化学实验。微型化学实验对化学课堂教学有如下特点:一、微型化学实验操作简便,安全高中常规实验比较多,有毒的实验过半。固体有毒残留物较好处理。气体有毒残留物不便于回收,故很多学校就配了通风橱,把有毒气体抽到大气中,仅仅是转移了污染物,采用微型实验可将污染降低到 The so-called micro-chemical experiments, is to use as little as possible chemical reagents to obtain the required chemical information experimental methods and techniques, it has two outstanding features: micro-chemical experiments required less dosage of drugs; miniaturized instrumentation In the chemical experiments. Micro-chemistry experiments on chemistry classroom teaching has the following characteristics: First, the micro-chemical experiment is simple, safe high school routine experiments are more toxic experiments more than half. Solid toxic residues are better handled. Gas toxic residues are not easy to recycle, so many schools have a fume hood, the toxic gases into the atmosphere, just transferred contaminants, the use of micro-experiments can reduce pollution to
