对电位-pH曲线测定实验装置的改进

电位-pH曲线测定实验是物理化学实验的重要内容。针对多数物理化学实验教材使用很多的仪器的现象,我们改进了测定电位-pH曲线的实验装置。该实验装置的显著特点是操作简单,减轻了学生做实验时候的压力。利用该装置进行了多次实验,结果发现数据重复性好,师生评价极好。因此,利用此装置有效地提高了物理化学实验教学的效果。

The Improvement of Device for the Experiment of Determination of Potential - pH Diagram

The determination of potential - pH diagram was a very important content in Physical Chemistry Experiment. But it needed many instruments in many experimental textbooks. Hence, the improvement of new devices would be of considerable importance to the chemistry community. The improved device for the experiment of determination of potential - pH diagram was introduced. The device had an obvious feature that was operation convenient, which would relieve the pressure when the students do the experiment. By the improved device, the experimental data showed better repeatability, which obtained a good reputation and also improved teaching results.
