Abstract

Descriptions of the solubility of HC1 in water involving Raoult's Law have been shown to be inappropriate. Henry's Law constants (KH) for reactions of the form: HX(g) = H(aq) ++X(aq) - are recommended for strong acids on both theoretical and practical grounds. Solubilities of strong acids in electrolyte mixtures can be calculated using activity coefficient models and appropriate values of KH. A critical evaluation of experimental data yields KH equal to 2.04 × 106mol2kg-2atm-1 at 25°C for HCl. The solubility of weak acids, such as HF, is also discussed. © 1986.
