摘要：采用高阻抗法测得原电池的电动势及其温度系数,进一步测定了溶液pH值和液接电势,并计算出相关的热力学函数,结果与文献基本一致。实验证明,高阻抗法不仅操作简便,节省时间,并且实验结果更加准确可靠,适合在基础物理化学实验中推广使用。
High impedance method was used to measure the electromotance of original battery and the potential of standard zinc electrode. Furthermore both the pH and liquid junction potential of solution were obtained and the related thermodynamic function was also calculated. All these results were consistent with literature. It is indicated that high impedance method can be used to measure electromotance, the operation is much more simple and the result is much more accurate. So this method is very suitable for basic physical chemistry experiment.
