本文討論了用嚴格的熱力學處理方法是不可能測定單離子活度的。以pH測定為例,詳述了單離子活度a_(M+)測定的困難所在,解決方法和實際測定中的存在問題,以及與單離子活度有關的一些問題。
This paper discusses that determining single ion activity with strict thermodynamic treatment methods is impossible. With the pH determination as an example, the difficulties in determination of single ion activity a_(H+), the methods to solve the difficulties, the problems arising from practical determination. and some problems in relation to single ion activity have been presented in detail.
