THERMODYNAMICS OF AQUEOUS HYDROCHLORIC ACID FROM EMFS OF HYDROGEN-CHLORINE CELLS

Activity coefficients for 1.0 to 11.1 molal HCl in aqueous solution have been obtained from e.m.f. measurements of the cell H2(1 atm.)/HCl (m)/Cl2(0.1 atm.) over the temperature range 25° to 80° C. Partial molal thermodynamic functions for HCl at various molalities have been derived, under the standard conditions: 25° C. and p = 1 atm. Standard molal potentials for the chlorine-chloride electrode have been determined over the range 25° to 80° C. © 1968, American Chemical Society. All rights reserved.
