    Solvation equilibria in very concentrated electrolyte solutions (1973)
    Springer
    Journal of solution chemistry 2 (1973), S. 173-191 
    Details
    ISSN: 1572-8927
    Schlagwort(e): Calcium bromide ; calcium chloride ; hydration of ions ; hydrochloric acid ; lithium bromide ; lithium chloride ; osmotic coefficient ; perchloric acid ; potassium hydroxide ; sodium chloride ; sodium hydroxide ; solvation of ions

    Thema: Chemie und Pharmazie
    Notizen: Abstract A stepwise hydration-equilibrium model for aqueous electrolytes is developed and shown to give a good quantitative account of osmotic coefficients of strong, highly soluble electrolytes up to concentrations of 20–30 m. The main parameters needed are two equilibrium constants describing the stepwise hydration and the number of hydration sites. Choice of ion-size parameter has only a minor effect.

    Activity coefficient of hydrochloric acid in aqueous solutions of sodium chloride (1977)
    Springer
    Journal of solution chemistry 6 (1977), S. 385-392 
    Details
    ISSN: 1572-8927
    Schlagwort(e): Activity coefficient ; electrolytes ; mixed ; Harned coefficients ; hydrochloric acid ; mixed electrolyte solutions ; sodium chloride

    Notizen: Abstract Electromotive-force measurements of the cell $$Pt;H_2 \left( {g,1{\text{ }}atm} \right)|HCl\left( {{\text{m}}_A } \right),NaCl\left( {{\text{m}}_B } \right)|AgCl;Ag$$ have been made at temperatures between 5 and 45°C at values ofm A+m B of 0.1, 0.3809, 0.6729, and 0.8720 mole-kg−1. The activity coefficients of HCl in HCl/NaCl mixtures and the Harned coefficients α12 have been obtained. The change of α12 with total molality is consistent with the existence of binary interactions between H+ and Na+ ions. The linear variation of the relative partial molal heat content with the fraction of NaCl in the mixture suggests that an analog of the Harned rule exists for this thermodynamic quantity.

    Activity coefficient of hydrochloric acid in HCl/MgCl2 mixtures and HCl/NaCl/MgCl2 mixtures from 5 to 45°C (1980)
    Springer
    Journal of solution chemistry 9 (1980), S. 457-465 
    Details
    ISSN: 1572-8927
    Schlagwort(e): Activity coefficient ; electrolyte mixtures ; Harned coefficient ; hydrochloric acid ; ionic interactions ; magnesium chloride ; seawater

    Thema: Chemie und Pharmazie
    Notizen: Abstract Magnesium, the dominant bivalent cation in natural seawater, exerts a substantial influence on the patterns of ion interactions in this saline medium. Mean activity coefficients of hydrochloric acid in mixtures of this acid with magnesium chloride at four ionic strengths, namelyI=0.1, 0.3809, 0.6729, and 0.8720 mole-kg−1, were obtained from emf measurements of cells without liquid junction at nine temperatures from 5 to 45°C. The three highest ionic strengths correspond to seawater of salinities 20, 35, and 45‰, respectively. In addition, mixtures of HCl, NaCl, and MgCl2 were studied atI=0.6729, the molal ratio of NaCl to MgCl2 being maintained at 7.202 as in natural seawater. The Harned coefficients α1 2 were found to decrease slowly with increase in temperature. The trace activity coefficient of HCl in solutions of MgCl2 as well as in NaCl MgCl2 mixtures was found to be nearly identical with that measured earlier in synthetic seawater of the same ionic strength but containing NaCl, MgCl2, KCl, and CaCl2.

    The temperature variation of the Harned coefficient in the system HCl−NaCl (1980)
    Springer
    Journal of solution chemistry 9 (1980), S. 449-454 
    Details
    ISSN: 1572-8927
    Schlagwort(e): Activity coefficient ; electrolytes ; mixed ; Harned coefficient ; hydrochloric acid ; mixed electrolyte solutions ; sodium chloride
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie
    Notizen: Abstract The Harned coefficient measures the effect of an added electrolyte on the activity coefficient of another electrolyte. It is composite, depending partly on properties of solutions containing only one electrolyte and partly on the magnitude of a coefficient characteristic of interaction between two like charged ions in the mixed electrolyte solution. From the meager data available, the latter coefficient depends little upon temperature. The consequences of assuming temperature independence are discussed.

    The system H2O−HCl−NH4Cl at 25°C: A study of Harned's rule (1974)
    Springer
    Journal of solution chemistry 3 (1974), S. 837-845 
    Details
    ISSN: 1572-8927
    Schlagwort(e): Activity coefficient ; ammonium chloride ; Harned's rule ; hydrochloric acid ; mixtures of electrolytes
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie
    Notizen: Abstract Electromotive-force measurements of cells containing hydrochloric acid and ammonium chloride at constant total molality have been used to determine the variation of the logarithm of the activity coefficient of hydrochloric acid with change in the amount of ammonium chloride in the solution. The results are interpreted in the light of the recent work of Pitzer, and it is found that Harned's rule holds for both electrolytes.

    Standardization of silver-silver chloride electrodes from 0 to 60°C (1980)
    Springer
    Journal of solution chemistry 9 (1980), S. 455-456 
    Details
    ISSN: 1572-8927
    Schlagwort(e): Activity coefficient ; hydrochloric acid ; silver—silver chloride electrode

    Thema: Chemie und Pharmazie
    Notizen: Abstract Reference values of the activity coefficient of hydrochloric acid at intervals of 5°C from 0 to 60°C are proposed. With their use, interlaboratory differences among silver—silver chloride electrodes can be eliminated.
