11.1 Solutions and Concentration | High School Chemistry

Chad introduces solutions in this lesson defining them in terms of the solute and solvent. He introduces the idea of solubility and what it means for a solute to be soluble vs insoluble. Chad then compares and contrasts unsaturated, saturated, and supersaturated solutions. Finally, he introduces the concept of concentration showing how it can be expressed in a variety of units including molarity, molality, mole fraction, and mass percent and shows how to convert between each of these units.
