Notizen: Abstract The Onsager-Fuoss-Chen theory of conductance for mixtures has been explored and compared with experimental results for the system HCl−MgCl2−H2O from 5×10−5 to 0.02 mol-kg−1 of water. In the theory, the higher order term O(ka) which involves the ion size parameter has been replaced by a linear term with an empirical constant. The theory including the additional linear term agrees well with the experimental results. The mixture effect on the equivalent conductance is small, but on the individual ionic mobilities is substantial.

Thema: Chemie und Pharmazie

Notizen: Abstract An absolute determination of aqueous electrolytic conductivity has been made for primary standards 0.01D and 0.1D (demal) potassium chloride solutions over the temperature range of 0 to 50°C in 5 degree intervals. A cell with a removable center section of accurately known length and area was used for the measurements. Values were adjusted to be in conformity with the ITS-90 temperature scale. The overall uncertainty over the entire temperature range is estimated to be 0.03%. Values at 25°C for 0.01D and 0.1D KCl solutions are 0.0014086 and 0.012852 S-cm−1, respectively.

Schlagwort(e): Activity coefficient ; amino acid ; EMF ; first dissociation constant ; HEPES ; glycine ; MOPSO ; ionic interaction ; hydrochloric acid

Quelle: Springer Online Journal Archives 1860-2000

Thema: Chemie und Pharmazie

Notizen: 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.
