Abstract

In the previous report, it was inferred that the quasi/equal transference numbers of hydrogen and hydroxyl ions exist in stationary electrolysis and Svensson's isoelectric focusing (IEF). The purpose of the report is to prove this inference. Based upon some basic physical chemistry data, the transference numbers of H+ in HBr, HCl and HI solutions and of OH- in KOH solution were compared by the relative judgment expressions (R-r) defined from themoving chemical reaction boundary equation (MCRBE). The results manifest that even the limited values of R-r, for the reaction electrolyte systems ofHCl-KOH, HBr-KOH, HI-KOH and H2SO4-KOH are quite high (0.07-0.14), as compared with those limited values (0.02-0.03) for the reaction electrolytes ofHCl-NaOH, HBr-NaOH, HI-NaOH and H2SO4-NaOH, however one can conclude that the quasi/equal transference numbers of H+ and OH- exist in the systems of HCl-KOH, HBr-KOH, HI-KOH and H2SO4-KOH, when the system should not be diluted infinitely. Thus the findings demonstrate the inference-the existence ofquasi/equal transference numbers of hydrogen and hydroxyl ions in stationary electrolysis and Svensson's IEF.
