Abstract
Mutual diffusion coefficients measured on the volume-fixed frame of reference are reported for KSCN-H2O at 25°C over the concentration range 0.0 to 10.26 mol-dm−3. The diffusion coefficient at infinite dilution was obtained from limiting ionic equivalent conductances of K+ and SCN−. Low concentration conductances of KSCN-H2O at 25°C used to obtain the limiting ionic equivalent conductance of SCN− are reported. Values of density and viscosity for this system are reported from 0.0 to 10.30 mol-dm−3. Osmotic coefficienss of KSCN-H2O at 25°C were measured by the isopiestic method. These are reported over the concentration range of 0.30 to 24.94 molal (saturation). Values of thermodynamic diffusion coefficients for the concentration range 0.0 to 10.26 mol-dm−3 are tabulated. Results are compared to other potassium salts with monovalent anions at 25°C.
