The acid-base properties of the ZnBr2-NaBr melts at 623 K were investigated on the basis of the electromotive force measurements of a zinc-zinc concentration cell. The following two chemical equilibria were postulated to describe the acid-base character of the melts ZnBr2 + Br- = ZnBr-3 K1 ZnBr-3 + Br- = ZnBr-4 K2 The equilibrium constants K1 and K2 were determined to be 5.0 × 102 and 1.0 × 102, respectively, at 623 K. The acidity of ZnBr2-NaBr melts is essentially weaker than that of bromoaluminate melts.
