摘要
Differential diffusion coefficients of ammonium monovanadate in water at 25degreesC and at concentrations from 0.001 to 0.05 mol-dm(-3), have been measured using a conductimetric cell and an automatic apparatus to follow diffusion. The cell uses an open-ended capillary method and a conductimetric technique is used to follow the diffusion process by measuring the resistance of solutions inside the capillaries at recorded times.
