“银氨配离子配位数的测定”是全国高师统编的《无机化学实验》中的实验内容之一。该实验操作简便易行,具有一定的综合性。但在实验过程中,AgNO_3的大量消耗且不说,尤其使用大量氨水,使得实验操作者处于严重的氨气味的熏呛之中,对学生的身体健康及操作训练都极为不利。由于以上种种原因,许多学校不得不将该实验内容删掉。那么如何将该实验的某些条件进行改进呢?我们在实际工作中采用了微型实验方法进行了尝试,并获得满意的结果。
“Determination of coordination number of silver ion with ion” is the national higher normalization of “inorganic chemistry experiment” one of the experimental content. The experimental operation is simple and easy, with a certain degree of comprehensiveness. However, during the experiment, the heavy consumption of AgNO_3, not to mention it, especially the use of a large amount of ammonia, made the experimenter suffer from the serious smell of ammonia and was extremely unfavorable to the health and operation training of students. Due to the above reasons, many schools have to delete the experiment contents. So how to improve some of the conditions of the experiment? We used in the actual work of the micro-experimental methods have been tried, and get satisfactory results.
