Abstract:
Proton and deuteron mobility in normal and heavy water solutions of some alkali halides (NaCl,
KCI, KBr and KI) and tetra-alkylammonium bromides (where alkyl is Me, Et, Pr or Bu) is measured
polarographically and the diffusion coefficients calculated from a corrected Ilkovic equation. The
results are analysed in terms of the effect of electrolyte concentration on the excess or Grotthuss
mobility of the hydrogen and deuterium ion. The results raise some questions about the accepted
mechanism for the transport of the proton and deuteron in solution.
