Learning Target 3.3.1: I can explain the dynamic process by which a solution is formed when one or more solute dissolve in a solvent. I can calculate solution concentration in terms of molarity, percent concentration, and parts per million.
Goals:
3.3.1.a I can define the terms solute, solvent, and solution.
3.3.1.b I can identify a solvent and a solute in a given solution.
3.3.1.c I can explain the process of dissolving on a molecular level.
3.3.1.d I can calculate I can calculate solution concentration in terms percent mass and percent volume.
3.3.1.e I can calculate solution concentration in terms of molarity.
3.3.1.f I can calculate solution concentration in terms of parts per million and parts per billion.
Solutions are homogeneous mixtures of gases, liquids, or solids. Every solution is composed of a solute(s) dissolved in a solvent. This lesson/unit focuses on liquid solutions that are composed of one or more solids dissolved in a liquid, usually water. Dissolving is an active process and isn’t considered complete until every solute molecule is surrounded by solvent molecules. Chemists use several ways to calculate and express solution concentration: percent mass, percent volume, molarity, parts per million, and parts per billion.
