“…Presumably the methanol in the solvent mixture constitutes an excess sufficient to cause predominant amphiprotic solvent characteristics. Van der Heijde and Dahmen (17), working in the 0.01 7 range, observed that the apparent purity of uncharged oxygen acids in amphiprotic solvents was enormously enhanced.…”

A coulometric-potentiometric procedure for the determination of relative acidity scales of acetone, methylethyl ketone, methyl-isobutyl ketone and propylene carbonate is described. The range of the relative acidity scale of a solvent was determined from the difference between the half-neutralization potential of perchloric acid and that of tetrabutylammonium hydroxide. The perchloric acid was generated in situ from a hydrogen-palladium electrode in presence of sodium perchlorate or tetrabutylammonium perchlorate as the supporting electrolyte. The electrode pairs glass-SCE and (H 2 /Pd) ind -SCE were applied for the measurement of the half-neutralization potentials of the acid and base. A wider range of relative acidity scale of the solvents was obtained with the glass-SCE electrode pair and tetrabutylammonium perchlorate as the supporting electrolyte.

“…Organic bases in nitromethane have been studied and a linear relationship between the relative strength of these bases in nitromethane and water was found (7). The factors that may influence the half-neutralization potential of acids and bases in different solvents have been outlined (8). In all these investigations, a straight-line relationship was noted between the relative strengths of acids in water and in nonaqueous media.…”
