Lozinskaya, Yu. Dedkov] The quantitative characteristics of protolytic processes in systems of H-resorcinol, beryllon III, and H-aminophenol reagents were determined by potentiometric titration graphically and using calculations. Diagrams were built of the speciation of these reagents in the pH range 2-13 and of the distribution of their mole fractions in the solution at given pHs. The existence of the azo-hydrazone tautomeric equilibrium was demonstrated for the H2R3− species of H-resorcinol. Pleiades Publishing, Ltd., 2007 Lozinskaya E. Kursk State University, ul.
