Abstract

Judgment expressions for a moving or stationary chemical reaction boundary(MCRB, SCRB) and isoelectric focusing (IEF) are defined from the moving chemical reaction boundary equation (MCRBE). The judgment expressions are tested with experiments cited in the literature and with those of a moving precipitate boundary formed by the reaction electrolytes CoCl2 and NaOH, coupled with the background electrolyte KCI. The judgment expressions are also used in comparisons between the transference numbers of the hydrogen ion in HBr, or HCl or HI solution with concentrations varying from infinite to 0.05 mol l(-1) and of the hydroxide ion in NaOH solution ranging from infiniteconcentration to 0.01 mol l(-1). The results show that predictions made with the judgment expressions are in agreement with experiment, that the judgment expressions are useful and convenient for judging the :movement of an MCRB and for comparisons of transference numbers of positive and negative reaction ions such as hydrogen and hydroxide ions in IEF. In addition, the results also display the existence of the equal (or quasi-equal) transference numbers of hydrogen and hydroxide ions in Svensson's IEF..
