Abstract

A Pt,H₂—AgCl,Ag e.m.f. cell is described whereby accurate measurements may be obtained from additions of stock solutions. Measurements with HCl + H₂SO₄ mixtures are used to evaluate the dissociation constant of the HSO^– ₄ ion at 25°C. A method of extrapolation is described which aims at reducing uncertainties due to the ion size parameter. Some previous measurements with e.m.f. cells are also re-examined.
