The apparent pK a of dyes in water-in-oil microemulsions depends on the charge of the acid and base forms of the buffers present in the water pool. Extended principal-component analysis allows the precise determination of the apparent pK a and of the spectra of the acid and base forms of the dye. Co
A new water-soluble chromogenic reagent, namely 2-(2-thiazolylazo)-5-[(N,N-dicarboxymethyl) amino]benzoic acid (TADCAB), is described in this paper. Its synthesis and spectrophotometric behaviors have been studied thoroughly. Its color reactions with various metal ions were investigated. The acid di
