The solubilities of AgBrO/sub 3/ in H/sub 2/O and D/sub 2/O were deternflned at 14.7, 26.6, and 55.6 deg C, using LiClO/sub 4/ to vary the ionic strength. The Debye-Heckel equation was used for the activity coefficient in the solubility product equation. The following thermodynamic functions for AgBrO/sub 3/ solubility in R/sub 2/O and D/sub 2/O, respectively, at 25 deg C were calculated: DELTA F deg = 6.83 and 6.62 kcal/mole, DELTA H deg = 11.7 and 12.5 kcal/mole, and DELTA S deg = 19.7 and 21.8 cal/deg-mole. It is shown that the lower solubility in D/sub 2/O is due to a larger enthalpy effect and hydration energy in D/sub 2/O. The entropy of crystalline AgBrO/sub 3/ is calculated to be 36.3 plus or minus 1.5. (D.L.C.)
