Part 4: Solubility & Concentration Some substances dissolve easier than others. This property is called “solubility” Definition: solubility the ____________ of a solute that will dissolve in a certain – amount of solvent. Substances have different solubility. Some will dissolve completely in water , while others will dissolve only a small amount. The amount of solute dissolved in a solvent affects its concentration. Definition: _______________ a description of the amount of a solute in a certain – amount of solution. Think of concentration as being how a solution is. “strong” substances have lots of solute. “Concentrated” substances only have a little solute. “Diluted” When a solvent can no longer hold any more solute, we called it “saturated”. Definition: saturated solution a solution that ___________ dissolve any more of a – solute. Definition: unsaturated a solution that _________ hold more solute. – Sometimes, a solvent can be made to hold more solute than normal. The solution is called “supersaturated”. Definition: supersaturated a solution that has _________________________. – A HOT solution can hold lots of solute. When it COOLS, it becomes supersaturated. Supersaturated solutions are unstable. The extra solute can out” if the solution is shaken! “fall
