Temperature and salinity dependence of molar absorptivities of thymol blue: Application to the spectrophotometric determination of pH in estuarine waters
Molar absorptivities of thymol blue have been determined in synthetic solutions of ionic strength ranging from 0.1 to 0.7 Mw. The solutions were buffered to pH 11.5 in order to characterize the absorption spectrum of the basic form of the indicator and to pH 5.0 to characterize the HI– form. The ext...
