Chapter Objectives
At the end of this unit students will be able to
1. define the properties of acids and bases.
2. compare and contrast acids and bases as defined by the theories of Arrhenius, Bronsted-Lowrey, and Lewis
3. describe how [H⁺] and [OH^-] are related in an aqeous solution.
4. classify a solution as neutral, acidic, ior basic given hydrogen ion or hydroxide ion concentration.
5. convert hydrogen ion and hydroxide ion concentrations into pH values.
6. describe the purpose of an acid-base indicator.
7. define strong and weak acids and bases.
8. define the products of an acid-base reaction.
9. explain how acid-base titration is used to calculate the concentration of an acid or a base.
10. explain the relationship between equivalence point and end point of a titration.
11. describe when a solution of a salt is acidic or basic.
12. demonstrate with equations how buffers resist changes in pH.
