Emf measurements have been made in cells without liquid junction of the type Pt;H2(1 atm)|HX(m1),MX(m2)|AgCl;Ag, containing mixtures of (i) HCI and (CH3)4NCI and (ii) HCI and (C2H5)4NCI, in different proportions, but at constant total ionic strength (μ= 3, 2, 1, 0.5, 0.2, 0.1). Measurements have been carried out at 10 ΔC intervals, over the temperature ranges 5-35 ΔC. The Ag|AgCI electrodes used, prepared by the thermoeiectrolytic method, gave closely agreeing results. The values for the standard electrode potential E Δ and the interaction coefficient α12 for each constant total ionic strength mixture at all the four temperatures have been evaluated by the computerized least-squares method. Interpretation of the results has been made in the light of the recent work of Pitzer. © 1978, American Chemical Society. All rights reserved.

Electromotive force measurements have been made in cells without liquid junction of the type Pt,H2(1 atm)|HCI (mA),MCI (mB)|AgCI,Ag, containing mixtures of (I) HCI and CH3NH2•HCI, (H) HCI and (CH3)2NH•HCI, and (III) HCI and (CH3)3N•HCI in different proportions, but at constant total molality (m = 3, 2, 1, 0.75, 0.5, 0.25, 0.1). Measurements have been carried out at 10 °C Intervals, over the temperature range 5-35 °C. The values of the standard electrode potential, E°, and the Harned interaction coefficient, QA for each constant total molality mixture at all four temperatures have been evaluated by the computerized least-squares method. The measured activity coefficients of HCI in all the mixtures at all four temperatures have been found to obey Harned’s rule. Interpretation of the results has been made in terms of the multicomponent ionic equilibrium theory of Lim (“all mixing coefficients”). Activity coefficients of all three substituted ammonium chlorides in the different mixtures at all four temperatures are derived. © 1991, American Chemical Society. All rights reserved.

Activity Measurements in Aqueous Mixed Electrolyte Solutions. 5. Ternary Mixtures off (i) Hydrochloric Acid, (ii) Mono-, Di-, or Trimethylammonium Chloride, and (iii) Water of Constant Total Molality

Activity coefficients of hydrochloric acid in aqueous mixed solutions with guanidinium chloride have been measured by using cells without liquid junction, of the type Pt,H2(1 atm)|HX(mA),MX(mB)|AgCl,Ag, containing mixtures of HCl and (NH2)2C═NH·HCl in different proportions, but at constant total molality (m = 3.0, 2.0, 1.0, 0.5, 0.25, 0.1). Measurements have been carried out at four different temperatures, viz., 278.15, 288.15, 298.15, and 308.15 K. The measured activity coefficients of hydrochloric acid in the mixture have been found to obey Harned's rule. Interpretation of the results has been made in terms of Scatchard's and Pitzer's equations. It has been found that the latter gives a better fit of the experimental data but the former is reasonably adequate. Activity coefficients for guanidinium chloride in the mixtures are derived by using both the equations. © 1988, American Chemical Society. All rights reserved.

ACTIVITY MEASUREMENTS IN AQUEOUS MIXED ELECTROLYTE-SOLUTIONS .3. HCL-CACL2 MIXTURES OF CONSTANT TOTAL IONIC-STRENGTH

Emf measurements have been made in cells without liquid junction of the type H2/HX (m1), MXn(m2)/AgCl, Ag . . (I) containing mixtures of HCl and CaCl2 in different proportions, but at constant total ionic strength (I = 2, 1, 0.5). The measurements have been carried out at 5°C intervals over the temperature range 5-35°C. AgAgCl electrodes prepared by two different methods (thermal and thermoelectrolytic) were used of which the thermoelectrolytic electrodes were found to give more consistent results. The results when extrapolated properly lead to E° values at the different temperatures which agree well with those reported in literature. The application of the Pitzer method leads to the calculation of the ionic interaction coefficients α12 and α21, at the different constant ionic strengths. The nature of variation of these α's with the total mixture ionic strength at different temperatures has been considered. © 1981.
