摘要:在化学实验中,在得到铜锌硫酸原电池实验结果后,发现其与理论有较大差别,其实验效果与Zn片和Cu片的纯度、硫酸溶液浓度、电极面积、电极间距离、外电路中的电阻以及电极的表面状态有关。别外,实验温度、接触面积和接触的良好程度对实验也有影响。 口袋领域关键词:锌铜原电池 影响因素视频客服系统
Abstract: in the chemical experiment, get in copper zinc sulfuric acid battery after the experimental results show that the theory and have bigger difference, the experimental effect and Zn piece of Cu and the purity of sulfuric acid solution concentration, and electrode area, the distance between the electrode, the resistance of the electrodes and deoxidization device on the surface. Don’t outside, the temperature, the contact area and the degree of good contact experiment may also be affected.铁橡栎

前言
把稀H2SO4溶液作电解质,铜和锌作两极,并用若干导线连接铜片和锌片,在导线中间接入一个电流表。锌片会逐渐溶解,铜片上有气泡产生,电流表指针发生偏转。本文对其影响因素进行探讨。水过滤板
实验原理
原电池是化学能转化为电能的装置,把锌板和铜板水平放入盛有稀硫酸的烧杯里,用选有电流计的导线连接两极时,可以观察到三个重要的现象:锌片溶解,铜片上有气泡逸出,导线中有电流通过。锌电极发生的电极反应是:工字钮
