Abstract

|
The effect of pressure on solvation of potassium chloride was studied by the density and viscosity measurements of water-methanol systems and the conductance measurements of KCl in this systems. These were used to calculate the r-function of KCl. It was found that the r-function of KCl which is 0.613 at 25℃ and 1 bar in water was continuously decreased to the minimum point and enhanced with increasing the composition of methanol. At high pressure, the r-function of KCl was similar to that of normal pressure. But r-function decreased with increasing pressure at the specific component of methanol.
