MODIFIED LATENT PROJECTIONS AND ITS APPLI CATIONS IN 2-DIMENSIONAL PHTITRATION

A modified latent projection is proposed based on the characters of fi rst in and first fixed feature of the titrative distributive coefficie nts of monoacids or monobases that have different pK. The single varia nt region is defined and the transfer vector is derived. Grey system w hich consists of two monoacids (or bases) mixtures can be ananyzed by this method. The pure titrative distributive coefficients and concentr ations for p-chlorophenol and o-chlorophenol mixtures are obtained by using two-dimensional pH titrative data and the modified latent projec tion.
