Saturated and Unsaturated Solutions

Saturated Solutions and Solubility. Solubility Solubility: refers to the mass (how much in grams) of solute that can dissolve in a given amount of solvent.

Solutions Mixtures: - Heterogenous Mixture: substances that make up the mixture are not spread uniformly throughout the mixture. - Homogenous Mixture:

Saturation of Solutions  A solution that contains the maximum amount of solute that may be dissolved under existing conditions is saturated.  A solution.

Solubility & Concentration Solutions Solubility & Concentration

A. Concentration Concentrated solution large amount of solute Dilute solution small amount of solute

A. Concentration % by Volume usu. liquid in liquid EX: 10% juice = 10mL juice + 90mL water % by Mass usu. solid in liquid EX: 20% NaCl = 20g NaCl + 80g water

A. Concentration UNSATURATED SOLUTION more solute dissolves no more solute dissolves SUPERSATURATED SOLUTION becomes unstable, crystals form concentration

B. Solubility Solubility maximum grams of solute that will dissolve in 100 g of solvent at a given temperature varies with temperature based on a saturated solution

B. Solubility Solubility Curve shows the dependence of solubility on temperature

B. Solubility Solids are more soluble at... high temperatures. Gases are more soluble at... low temperatures. high pressures (Henry’s Law).
