This paper reports precise conductance values for dilute (< 4 × 10–3 mol dm–3) aqueoussolutions of twenty-three 2:2 salts at 25 °C. Alkaline earth metal sulphates, thiosulphates, dithionates, tetrathionates, ethyl-, n-propyl-, n-butyl-disulphonates and acetylenedicarboxylates were studied. The results are analysed by means of the Lee–Wheaton conductance equation in terms of the limiting molar conductivity

This invention relates to solutions of dithionic acid and/or dithionate salts for use in metal finishing processes such as those used for the cleaning, activating, electroplating, electroless plating, conversion coating and/or other pre-treatment or post-treatment of a metallic surface. In particular the solutions are a useful electrolyte for the electroplating of metallic coatings, especially, Sn, Cu, Ni, Zn and precious metals, onto metal or plastic substrates and/or other surfaces.
