    Notes: Abstract The standard potential of the mercury:mercurous sulfate electrode in aqueous solution at 25°C is determined in terms of the Weston saturated and Clark saturated standard cells. Eight electrode combinations involving cadmium-amalgam or zinc-amalgam electrodes and one lead-amalgam electrode are employed with the emf of the standard cells. A best value of 0.61544 V was obtained that agrees within 0.09 mV with the value previously reported by Harned and Hamer.

    Investigation of the interaction of HCl and three amino acids, HEPES, MOPSO and glycine, by EMF measurements (1992)
    Springer
    Journal of solution chemistry 21 (1992), S. 311-321 
    Details
    ISSN: 1572-8927
    Keywords: Activity coefficient ; amino acid ; EMF ; first dissociation constant ; HEPES ; glycine ; MOPSO ; ionic interaction ; hydrochloric acid
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Ionic interaction in the three systems Hcl-HEPES (N-2-hydroxyethylpiperazine-N′-2-ethanesulfonic acid), HCl-MOPSO (3-(N-Morpholino)-2-hydroxypropanesulfonic acid), and HCl-glycine have been studied in terms of their mutual influence on the respective activity coefficients of each component. Activity coefficients for each component of the three systems are calculated from emf measurements of solutions containing HCl and the amino acid in a H2/solution/AgCl,Ag cell at 25°C. The first dissociation constant of HEPES at 25°C has also been determined using emf and pH titration measurements.
