- Descripción
- The diffusion coefficient of cupric ion in sulphuric acid solutions containing glycerol from 0 to 10 M has been determined with the aid of the rotating disk electrode. The viscosity of the solutions has also been measured. Experiments covered a temperature range from 18 to 40°C. The experimental results are in agreement with the predictions of the Einstein-Stokes theory for diffusivity and viscosity. The ratio Dη/T is (2·23 ± 0·31) × 10−10 cm2 poise/s°K and it is reasonably constant within the whole range of viscosity and temperature investigated.
Le coefficient de diffusion de l'ion cuivre(II) dans des solutions d'acide sulfurique contenant du glycérol d'une concentration de 0 à 10 M a été déterminé au moyen d'une electrode à disque tournante. La viscosité des solutions a également été mesurée. Les expériences furent effectuées à une témperature entre 18 et 40°C. Les résultats se rapprochent d'une façon satisfaisante des prédictions de la théorie d'Einstein-Stokes pour la diffusivité et la viscosité. Le rapport Dη/T est (2,23 ± 0,37) × 10−10 cm2poise/sec°K et reste assez constant dans tout le champ de la viscosité et de la témperature étudiés.
