Interrelation between dielectric permittivity of solutions and disociation of cesium, strontium, cerium(3) dicarbollides in nitrobenzene

Dielectric permittivity and molar electric conductivity of solutions of chlorinated cobalt dicarbollide (CCD) and Cs, Sr, Ce dicarbollides in nitrobenzene were determined. By the experiment results dissociation constants of HCCD, CsCCD, Sr(CCD)2, Ce(CCD)3 solutions were calculated. It is shown that dependence of dissociation constant logarithms on dielectric permittivity is described by linear equation. The dependence mean deviation from experimental values of dissociation constant does not exceed 0.2 logarithmic units
