从定量的角度探究单液铜-锌原电池实验的改进方案

Experiment Improvements of Copper-Zinc Primary Battery with Single Electrolyte Solution from Quantitative Perspective

对铜-锌原电池中的锌片做半汞齐化处理,分别将锌片汞齐化的一端和非汞齐化的一端插入稀硫酸中,测量电池的电流和电压.通过2次实验的测量对照计算得出电流、电压损失百分比,从而定量地描述锌片上产生的氢气,并将此方法应用于改进单液原电池实验.从锌电极、铜电极和稀硫酸浓度3个方面采取改进措施,从而尽可能减少锌片上的气泡.

This paper used half-amalgamation zinc plates to do the experiment of copper-zinc primary battery,immersed the amalgamating end and non-amalgamating end of zinc plates into dilute sulphuric acid successively and measured the current and voltage. Then this article calculated the percentage loss of current and voltage by comparing the amalgamating side and non-amalgamating side so that H2 produced on zinc plate could be represented quantitatively. This experiment was improved from three aspects: zinc electrode, copper electrode and the concentration of dilute sulphuric acid, in order to reduce bubbles from zinc plate.
