Practice: The solubility of KClO3 in water at 30ºC is 10 g per 100 mL of water. A 0.95 M solution of KClO3 in water at 30ºC is:
When an ionic solid dissolves, ions leave the solid and become dispersed in the solvent. Three possible aqueous solutions can be formed: saturated, unsaturated and supersaturated.
Concept #1: Solution Equilibrium
Concept #2: Types of Aqueous Solutions
Example #1: The solubility of a substance is 56 g per 100 mL of water at 20° C. A solution of this substance is prepared by dissolving 80 g in 100 mL of water at 75° C. The solution is then cooled slowly to 20° C without any solid forming. The solution is:
