Descrição

Differential diffusion coefficients of potassium sulfocyanate in water at 298.15 K, and at concentrations from 0.001 M to 1 M, have been measured using a conductimetric cell and an automatic apparatus to follow diffusion. The results are discussed on the basis of the Onsager-Fuoss and Pikal models. The cell uses an open-ended capillary method and a conductimetric technique is used to follow the diffusion process by measuring the resistance of a solution inside the capillaries, at recorded times. http://www.sciencedirect.com/science/article/B6TGR-454V3HS-F/1/0b8c4db83834abdfd70dcbe9eecd2b88
