摘要
介绍了等体积法原理,通过等体积法原理测定了25～45℃苯-水-乙醇三元体系的等温会熔点,并计算了会溶点中苯的质量分数与温度的线性规律。通过误差分析得出,实验的系统误差小于0.015。偏差小于0.01。可以作为实验内容补充到物理化学实验教学中。
The equal - volume titration method was explained and was used to measure isothermal consolute points of benzene - water - ethanol ternary solutions at 25 ~ 45＂C in this paper. The linear relation ship between the mass fraction of benzene and temperature was calculated, Results show that, the error is better than 0. 01 and the systematic error is better than 0. 015. This can be added in college physical chemistry experiment.
