Abstrakt: The ionization of 16 thiocarbonyl indicators of overlapping range has been used to establish an acidity function HTfor 10–90% sulfuric acid. Agreement with an earlier HTscale of Tissier and Tissier using different thiocarbonyl indicators is good. Protonation constants pKTH+derived by the classic Hammett–Deyrup approach are in good agreement with those derived by the Bunnett–Olsen relations, but in less satisfactory agreement with those derived by the Marziano–Cimino–Passerini relations.
