Partial Pressures of Gaseous Hcl and H2o Over Aqueous Solutions of Hcl, Alcl3, and Fecl3.
Equilibrium partial pressures of gaseous hcl and h2o over aqueous binary and ternary solutions of hcl and alcl3 were calculated or estimated in the range of 20 deg. to 110 deg. C, and up to saturation with alcl3. 6H2o. The results were extended to solutions containing less than 10 wt-pct fecl3 by assuming that fecl3 and alcl3 are equivalent on the molar basis, since both salts have trivalent cations with a common anion. The ionic activity coefficient of hcl and the equilibrium constant for dissolution of gaseous hcl were also computed.
