Abstract

The standard e.m.f's (po = 101325 Pa) for the cell H2/HCl/AgCl/Ag in (acetonitrile + water) containing mass percentages of acetonitrile from 0 to 50 have been obtained as a function of mole fraction x of acetonitrile and temperature (within the range from 288.15 to 308.15 K), using a one-stage multilinear regression method applied to the analysis of experimental e.m.f.'s. Thermodynamic functions (ΔGmo, ΔHmo, ΔSmo, and ΔCp, mo) for the cell reaction at T = 298.15 K have also been obtained as functions of x. A comparison is made with the corresponding quantities computed from separate analyses of e.m.f.'s for each experimentally investigated solvent composition (mass percentages of acetonitrile: 0, 5, 10, 15, 30, and 50).
