Description

Mutual diffusion coefficients (interdiffusion coefficients) have been measured of chromium(III) chloride in water at 298.15 K and 303.15 K at concentrations between 0.005 mol·dm-3 and 0.05 mol·dm-3 using a conductometric cell. The experimental mutual diffusion coefficients are discussed on the basis of the Onsager−Fuoss model. The equivalent conductance at an infinitesimal concentration of the chromium(III) ion in these solutions at 303.15 K has been estimated using these results. http://dx.doi.org/10.1021/je050003x
