The purposes of this study are to find the expansion profile of solutions and to investigate the saturation behavior of solutes of various systems operated at constant temperature. Carbon dioxide was used to expand a number of solutions with a technique of low expansion rates, that is, CO 2 was introduced above the liquid and diffused into the saturated solution, while the solution temperature remained constant. Higher rates of expansion, either by stirring the liquid or by bubbling CO 2 through the solution, which caused a rapid rise in temperature, are excluded in this paper. The solution expansion profiles were recorded and modeled with a derived equation. The distinct types of solute saturation behaviour caused by solution expansion are described.
