Unit 2: Aqueous Solutions

Learning Objectives for Unit 2 is located here.

Water is central to life in a biological sense but also chemical. Numerous reactions use water as a solvent system and can be referred to as aqueous solutions. To be discussed: general properties of aqueous solutions, molarity (concentration), precipitation reactions, solution stoichiometry and chemical analysis, and oxidation-reduction reactions.
