“…(11) The cell design, and the electrolytic method of deposition of these amalgam electrodes by K deposition on a mercury cathode from aqueous 0.5 mol · kg −1 KOH solution, were described earlier. (12) The verification of the K mole fraction x in the amalgam electrodes used was carried out potentiometrically, by measuring the e.m.f. E I of cell (I) at T = 298.15 K in pure aqueous medium at various molalities m of KCl.…”
