Standard potentials of the calcium amalgam electrode at various temperatures, with related thermodynamic functions

Thermodynamics of the amalgam cell {KxHg1−x| KCl (m)| AgCl | Ag }and primary medium effects upon KCl in { ethylene glycol + water }, { acetonitrile + water }, and { 1,4-dioxane + water } solvent mixtures

“…(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.…”

Thermodynamics of the cell: {NaxHg1−x|NaCl(m)|AgCl|Ag} in (methanol+water) solvent mixtures

“…(3) The cell design, the electrolytic method of preparation of these amalgam electrodes (by Na deposition on Hg cathode from aqueous 1 mol·kg − 1 NaOH solution), and the method of control of the mole fraction x of Na in amalgams were described earlier. (5) For all the flowing alkali-metal as well as alkaline-earth dilute-amalgam electrodes, (3) an important factor for accuracy and repeatability of results proved to be the homogenization of amalgams by storage overnight at T = 323 K with efficient stirring and under ultrapure N 2 flow before transfer to the two-capillary-tube amalgam dropper for the e.m.f. measurements.…”

“…(6) The thermostatic apparatus was described in an earlier paper. (5) The e.m.f.s. were measured by a Type 619 Keithley digital electrometer at NaCl molalities approximately up to the solubility limit in each solvent mixture considered.…”

Thermodynamics of the cell Pt | H2(p)| HCl (m)| AgCl| Ag and primary medium effects upon HCl in (glycerol + water) solvents

“…The thermostat was described in a previous paper. (23) In order to reach temperatures <273.15 K, a Type EN 850 Neslab flowthrough cooler was used.…”
