| Abstract: | This paper presents a model of the formation of hydrated and solvated ionic pair, nonhydrated monosolvate HNO3 · TBP (tri-n-butylphosphate), hydrated disolvate HNO3 · 2TBP, and semisolvate 2HNO3 · TBP, to which an unlimited number of HNO3 molecules can be added. The equilibrium was calculated using mole fractions. To calculate the mole fraction of free (not
bonded to solvates) water, we suggested an equation containing four parameters, three of which are determined from the data
for the independent TBP-H2O-diluent system. |
