    Ionization of Moderately Strong Acids in Aqueous Solution: Part 2—Further E.m.f. Studies of the Dissociation of the Bisulphatc Ion
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1973, 69 (1), 1973) Covington, A. K.; Dobson, J. V.; Srinivasan, K. V.
    New measurements on the cell: Pt,H2 | Na2SO4, NaHS04, NaCl | AgCl | Ag have failed to substantiate the original measurements made by Hamer forty years ago and subsequently reanalyscd many times. The range of values for the dissociation constant of the bisulphatc ion (K2 of sulphuric acid) is substantially in agreement with that obtained from the simpler cell in which sodium chloride was omitted and the mercury-mercury(I) sulphate reference electrode was used. K2 = 0.0113 ±0.0005 mol kg-1 at 25°C where the uncertainty arises from a range of reasonable choices for the ion-size parameter.

    Plateau potentials of the α+β palladium hydride electrode at temperatures between 25 and 195°C
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1972, 68 (4), 1972) Dobson, J. V.; Dagless, M. N.; Thirsk, H. R.
    The e.m.f. values of cells with respect to time, involving the platinum-hydrogen and (α+β) palladium hydride electrode in hydrogen-saturated aqueous electrolytes are reported between 25 and 195°C and 1–27 atm hydrogen pressure. Relative resistance measurements of the (α+β) palladium hydride electrode as a function of time are also reported under these conditions.

    Some Experimental Factors which Govern the Potential of the Palladium Hydride Electrode at 25 to 195°C
    (Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1972, 68 (4), 1972) Dobson, J. V.; Dagless, M. N.; Thirsk, H. R.
    A purpose of this paper is to present some of the experimental electrochemical properties of the palladium hydride electrode that have been found between 25 and 200°C. The electrode potentials of palladium hydride were studied in aqueous solutions of sodium hydroxide and hydrochloric acid, in the presence and absence of carbon dioxide and nitrogen. All potentials are measured with respect to a platinum-hydrogen electrode. Use of relative resistance is made to establish the hydrogen-palladium composition and potential dependency as a function of time, temperature and pressure. Some simple polarization studies are also reported on fully equilibrated palladium hydride electrodes.
