FIGURE 32.4 Potential dependence of the interfacial tension J and the capacity C for the interface between solutions of 5mM tetrabutylammonium tetraphenylborate in 1,2-dichloroethane and lOOmM LiCl in water. The potential scale E represents the Galvani potential difference relative to the standard ion transfer potential for tetraethylammonium ion, cP o EA+ = 0.02 V. 

Remarkable data on primary hydration shells are obtained in non-aqueous solvents containing a definite amount of water. Thus, nitrobenzene saturated with water contains about 0.2 m H20. Because of much higher dipole moment of water than of nitrobenzene, the ions will be preferentially solvated by water. Under these conditions the following values of hydration numbers were obtained Li+ 6.5, H+ 5.5, Ag+ 4.4, Na+ 3.9, K+ 1.5, Tl+ 1.0, Rb+ 0.8, Cs+0.5, tetraethylammonium ion 0.0, CIO4 0.4, NO3 1.4 and tetraphenylborate anion 0.0 (assumption).

Figure 5. Effect of the supporting electrolyte cation in the nitrobenzene phase on the relationship between interfacial potential and dye iodide (DiOC2(3)1) concentration. A, 0.01 mol /L tetramethylammonium tetrapheny lb orate B, 0.01 mol/L tetraethylammonium tetrap heny lb orate C, 0.01 mol/L tetrabuty-lammonium tetrapheny lb orate D, two identical curves, 0.01 mol / L tetraphenylarsonium tetraphenylborate and 0.01 mol / L crystal violet tetraphenylborate. (The crystal violet has no supporting electrolyte in the nitrobenzene phase.) The supporting electrolyte in the water phase is always 0.01 mol/L LiCl, except for curve E, which has no supporting electrolytes.
