Comparison of the Methods of Determining Stability Constants in the Linear Titration

The various methods of calculating the stability constants-Gorden method, Monte Carlo method, Bjerrumis formation function regression method,Curve modeling method, Direct computing method and Schwarzenbach method were compared. The practicability of these methods were proved by experimental results,respectively. And the suitable systems for various methods were obtained as follow:the Gorden method was suitable to the systems of mixture and unknown acids;the Monte Carlo method to the system of polybasic acids;the formation function method to the systems of interlock neutralisation;the direct computing method to the unknown systems of monobasic acids.
