AP Notes Chapter 14 Solutions and Their Behavior
Solution a homogeneous mixture of two or more components Solute component(s) present in lesser quantity Solvent component present in greater quantity
A saturated solution contains the maximum quantity of solute that dissolves at that temperature. An unsaturated solution contains less than the maximum quantity of solute that dissolves at that temperature. Supersaturated Solutions contain more than is possible and are unstable.
