Abstract
From emf E measurements of the reversible cell
at 0.01<m<0.1 mol-kg−1 in 70% (w/w) ethanol-water solvent mixtures over the temperature range from −10 to +40°C, the standard emf E° of the cell with the related thermodynamic functions of the cell reaction and the mean molal activity coefficients of hydrochloric acid have been determined. The present E data at 70% (w/w) ethanol have been combined with earlier data at ≤50% (w/w) ethanol to be analyzed critically by a one-stage multilinear regression method leading to an optimized set of E° values for the range 0–70% (w/w) ethanol which are essential for the assessment of pH standards in these solvent media.
