Ionization and dissociation equilibria in liquid SO/sub 2/. 12. The behavior of tetrahedral ions
- Boston Univ., MA
Electrolytic conductance of their solutions in liquid sulfur dioxide over a wide range of concentrations was measured for the 21 ionophores, Me/sub 4/NCl, Me/sub 4/NClO/sub 4/, PhMe/sub 3/NBr, PhMe/sub 3/NCl, PhMe/sub 3/NI, Et/sub 4/NI, Pr/sub 4/NCl, Pr/sub 4/NBr, Pr/sub 4/NI, Bu/sub 4/NBr, Bu/sub 4/NI, Bu/sub 4/NPc, (i-Am)/sub 4/NBr, (i-Am)/sub 4/Ni, (i-Am)/sub 4/NB(i-Am)/sub 4/, (i-Am)/sub 3/NHBr, Hex/sub 4/NI, Ph/sub 4/AsC1, Ph/sub 4/AsI, Ph/sub 4/AsPc, and Ph/sub 4/PPc, at 273.15 K and other temperatures. Limiting equivalent conductances and dissociation constants were determined for these solutes by Shedlovsky's procedure. Utilizing the data of this and other investigations, we calculated thermodynamic quantities for the dissociation equilibria of many of the solutes. Values of Bjerrum's contact distance parameter, a, were calculated from the equilibrium data and compared to sums of estimated ionic radii. Limiting ionic conductances were evaluated by a Fuoss-Coplan division of the limiting equivalent conductance of (i-Am)/sub 4/NB(i-Am)/sub 4/. Stokes radii were calculated for the ions employed. The results of the measurements are interpreted in terms of ion-ion and ion-solvent interactions.
