- Abstract:
- Conductance cells designed and used according to the van der Pauw method are suitable for the absolute determination of the electrolytic conductivity of solutions and they are more advantageous for this purpose than other calculable cells. Three designs of such cells have been constructed and tested by the author. Results of experimental investigations confirm theoretical expectations and indicate that such a cell can be employed to substitute for standards of electrolytic conductivity. An absolute determination of electrolytic conductivity of 0.01 and 0.1 kmol/m³ NaCl solutions, with an uncertainty lower than 0.1%, has been obtained by the author using the cell of a new design.
