Sažetak

The selective solvation of K+,Rb+and Cs+ ions has been studied
at 25 DCby solubility measurements. The solubility of tetraphenylboride
salts, KBPh4, RbBPh4 and CsBPh4 increases with the
addition of N,N-dimethylformamide (DMF) to methanol (CH30H)
solutions. From the solubility data, the solvation free energies
of the ions under consideration are evaluated on applying the
asymmetric tetraphenylarsonium-tetraphenylboride (ΔG° Ph4As+>
>ΔG° Ph4B-) assumption and their values are discussed.
