摘要
介绍了应用微型实验技术对基础化学实验中《碘化铅溶度积常数测定》实验进行改进应用的做法.结果表明,改进后的实验方法,主要仪器显著微缩,试剂用量大幅节省,实验时间大为减少,操作更为简便,废液排放量减少,教学功能和效果较好.
The method of measuring Ksp of PbI2 is improved by applying microexperiment.The result shows:the equipment could be minisized,the amount of reagent could be reduced,the time of experiment could be shortened,the operation was more simple,the emission amount of waste liquid was reduced.The bunction and ebbects of teaching was better.
