GIBBS ENERGIES OF TRANSFER OF SEVERAL ALKALI-METAL CHLORIDES FROM WATER TO SUCROSE WATER MIXTURES USING STREAMING AMALGAM ELECTRODES

The Gibbs energies of transfer of lithium chloride, sodium chloride an d potassium chloride from water to various sucrose-water mixtures at 2 98 K have been determined from emf measurements on the cell: Ag\AgCl\M Cl(m(1), aq)\M(Hg)\MCl(m(2), aq-sucrose)\AgCl\Ag Measurements have bee n made with streaming amalgam electrodes in solutions up to 0.1 mole f raction sucrose (68 wt.%). The results agree well with earlier work at quite low sucrose mole fractions (up to 0.02) and are consistent with the view that sucrose in solution does not solvate either the cation or the chloride ion to any significant extent.
