Abstract: A general expression of the relation among the component concentration, the volume of titrant and the solution pHin mixtures of several acids is derived under the fixed pHtitration condition. The expression is well suited to solve this equation by multivariate analysis methods.In this paper a mixed acid analysis is investigated by factor analysis. Several mixed systems were testified with satisfaction, the method is more reliable and simple.

Key words: Factor analysis, Tixcd pH titration, Multivariant analysis method
