摘要
通过改变凝固点降低法测定溶质摩尔质量实验中的搅拌装置,对一个经典的基础实验装置进行了改进,这种改进克服了实验过程中平衡温度不易观察的缺陷,实验效果明显提高.
A stiring equipment is amended in the experiment of molar mass by reduing freezing point.Improvement is done over a classical experiment,which overcomes the defects caused by the fluctuating temperatures.The result is outstanding.
