SURFACE-TENSION, VISCOSITY, VAPOR-PRESSURE, DENSITY, AND SOUND-VELOCITY FOR A SYSTEM MISCIBLE CONTINUOUSLY FROM A PURE FUSED ELECTROLYTE TO A NONAQUEOUS LIQUID WITH A LOW DIELECTRIC-CONSTANT - ANISOLE WITH TETRA-N-BUTYLAMMONIUM PICRATE

In view of very little progress reported in the study of the physical chemistry of systems which are miscible continuously from a pure fused electrolyte to a pure nonaqueous liquid with a low dielectric constant, a detailed study on several properties like surface tension, viscosity, vapor pressure, density, and compressibility is presented at different temperatures for anisole-tetra-n-butylammonium picrate (TP) over the full composition range. An attempt has been made to correlate the investigated properties. Good agreement between the molar free energy of viscous flow calculated from the Eyring equation and from the hole formation indicates that holes are essential entities from pure anisole to TP. Ultimately, the Scaled Particle Theory (SPT) has been employed to estimate the surface tension of the system with good agreement barring the asymmetry of the excess surface tension-composition curve.
