本文从热力学第一、第二定律出发,应用化学势的概念,推导出食盐溶液的浓度差与电动势的理论关系式,从而为银——氯化银电极探针测量食盐溶液的浓度提供了理论依据。提出了制作银—氯化银电极探针的工艺程序和技术。试验证明,用银—氯化银电极探针测量因食盐溶液中浓度差而产生的电动势值与理论值有较好的一致性。
Based on the first and second laws of thermodynamics, this paper deduces the theoretical relationship between the concentration difference of salt solution and electromotive force by applying the concept of chemical potential, and provides the theory for measuring the concentration of salt solution with silver-silver chloride electrode probe in accordance with. The process and technology of making silver-silver chloride electrode probe are proposed. Experiments show that silver-silver chloride electrode probe measurement of concentration difference due to salt solution generated electromotive force value and the theoretical value of a good agreement.
