Evaporation
Basic Facts
•Dissolved solids are non-volatile
•Density of Solution Increases with Solids Concentration
•Viscosity of Solution Increases with Solids Concentration
•B.P. of Solution Increases with Solids Concentration
•Solids precipitate as concentration rises above solubility
•Solution viscosity increases with temperature reduction
