✦ Synopsis

The electrode potentials of the system Ag(I)/Ag(O) in molten magnesium chloridepotassium chloride (325: 67.5 mol-%) at 475°C are reported to obey the Nernst uation. Using this as a reference, (apparent) standard electrode potentials for the systems Mn(II) Mn(O), 7 Zn(II)/ ZnK% TWYll(O), CWJWd(O~, WIWWO), FeWWe( Sn(WSnW, Pb(IWPb(O), Co(IW/Co@), Ni(II)/Ni(O), Cu(I)/Cu(O}, Sb(III)/Sb(O), Pd(II)/Pd(O), Pt(II)/Pt(O) and Au(I)/Au(O) have been determined. In all cases plots of electrode potential ZIS logarithm of solute mole-fraction are rectilinear and their slopes agree within a few mV with the calculated value of the Nernst slope (2.303 RT/nF). On the molefraction scale the (apparent) standard electrode potentials for the above systems are -1.2078, -0.
