摘要
根据pH操作定义求算pH值的量方程 ,当前存在两种表示形式 ,其原因是国际标准ISO和我国国家标准GB 310 2 .8中对pH操作定义采用的电池与我国实际惯用的pH操作定义选用的电池不同 ,通过推导 ,指出这种不同并不影响pH的测量结果 。
There are two different expression equations about the pH calculation based on the operational definition of pH.The reason is that the cell used to operational definition of pH in ISO and national standard GB 3102.8 is different than that in our internal convention. According to the inference,this paper indicates that the difference will not influence the measured result of pH.This research has references value in electrochemical analysis and physico-chemistry.
