Solubility studies in formamide: IV. Ionization constants of iodic and bromic acids in formamide from solubility measurements

The ionization constants of iodic and bromic acids in formamide have been determined at 25, 30, and 35°C from solubility measurements. The ionization constants of iodic acid are found to be 9.83 × 10^?2, 12.02 × 10^?2 and 12.14 × 10^?2, respectively, and those of bromic acid, 9.56 × 10^?2, 9.70 × 10^?2, and 10.15 × 10^?2, respectively, at 25, 30 and 35°C. Thermodynamic parameters associated with the ionization processes have also been determined.
