Solubilities of caesium and thallium(I) triphenylcyanoboronates and of caesium and mercury(II) tetraphenylboronates in alcohol + water mixtures; Transfer chemical potentials of the BPh 3(CN) −, BPh 4 −, TI +, and Hg 2+ ions

Abstract

Solubilities(298.2 K) are reported for caesium and thallium(I) triphenylcyanoboronates in water and in methanol-, ethanol-, and t-butyyl alcohol-water mixtures containing up to 40% (by volume) alcohol. Solubilities (298.2 K) are also reported for caesium tetraphenylboronate in t-butyl alcohol- and ethylene glycol-water mixtures and for mercury(II) tetraphenylboronate in t-butyl alcohol-water mixtures, again up to 40% (by volume) alcohol. From these data and published transfer chemical potentials (based on various extrathermodynamic assumptions) for appropriate ions, we have derived estimates for the transfer chemical potentials of BPh 3(CN) − and TT + to methanol, ethanol, and t-butyl alcohol-water mixtures, for BPh 4 − to t-butyl alcohol- and ethylene glycol-water mixtures, and for Hg 2+ to t-butylalcohol-water mixtures.
