The acid-base properties of the ZnBr[2]-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 ZBnr[2]+Br[-]=ZnBr[3][-] K[1] ZnBr[3][-]+Br[-] =ZnBr[4][2+] K[2] The equilibrium constants K[1] and K[2], were determined to be 5.0×10, and 1.0×10[2], respectively, at 623 K
