摘要
通过几年大学化学实验的教学,发现一些基础化学分析实验随着教学实践的发展,显示出很多弊端,如污染严重、学时效率低等问题。为了解决这些问题,同时对基础实验进行发展,发展了新的容量法与重量法对照测定钙的实验方法,并尝试用于基础化学分析实验。
Through years of the college＇s chemistry experimental teaching,the author has found that some basic chemical analysis experiments show a lot of drawbacks with the development of teaching practice,such as serious pollution and low efficiency.This paper has developed a new experimental method of determination of calcium based on volumetric and gravimetric method,which is attempting to apply to a basic analytical chemistry experiment.
