Abstract

This article brings to mind that the textbook acidity constants of the hydrohalic acids (except for HF) are erroneous because of outmoded conjectures about the HX solubilities. Here we invoke theoretical calculations of HX solubilities based on current solvation models. Although we do not claim to have provided the ultimate answer, it is safe to assume that the solubilities of both HCl and HBr are much higher than commonly surmised.
