Unit 9: Equilibrium, Acid/Base

Learning Objectives for Unit 9 is located here.

The chemistry of acids and bases occur in so many things you might not be aware of---from cooking to medicines to unclogging a sink. In addition to water, the principal substances of our tissues, muscles, and organs are proteins - polymers of amino acids joined by acid-base reactions. As you can see, the examples are endless! To be discussed: definitions of acids and bases, auto-ionization of water, pH scale, relative acid/base strength, relationships between Ka and Kb, and acid-base properties of salts.
