THE HYDROLYTIC BEHAVIOR OF THORIUMNIV)-PYROCATECHOL-3,5-DISULFONATE

· Journal of the American Chemical Society (U.S.)
Potentiometric measurements are described for aqueous systems containing 4: 1, 3:1, 2: 1, and 1:1 moles of Tiron (disodium pyrocatechol-3,5-disulfonate) per mole of thorium(IV) salt in 0.1 M potassium nitrate solution. For ligand/metal ratios of 1.5: 1 or higher the same compound is formed initially, regardless of the excess ligand present. The nature of the 1.5: 1 compound is established by spectrophotometric and potentiometric studies. Extensive hydrolysis of the metal chelate takes place at all ratios of ligand to metal ion studied, but no precipitation occurs over the wide pH range investigated. (auth)
