  1. Warm-Up: Brainstorm • What is an acid? • What is a base?

  2. Acids and Bases May 6th, 2013

  3. What is an acid? • Tastes Sour • Corrosive to metals • Contains [H+] ions (same as [H3O+]—Hydronium) • Bronstead-Lowry Theory  Proton donor (H+) • Arrhenius Acid increases conc. of [H+] ions

  4. Examples of an Acid • Battery Acid • Citrus juices • Stomach Acid • Vinegar

  5. Acid Terminology • Monoprotic • Can give 1 [H+] ion • HCl, HNO3 • Diprotic • Can give 2 [H+] ion • H2SO4 • Triprotic • Can give 1 [H+] ion • H3PO4 • Strong • Readily dissociates in solution • Weak • Partially dissociates in solution

  6. What is a base? • Bitter Taste • Feels slippery • Contains OH- ions • Bronstead-Lowry  Proton acceptor [H+] • Arrhenius  increases [OH-]

  7. Examples of Bases • Soap • Dark Chocolate • Antacid • NaOH

  8. Base Terminology • Strong • Readily dissociates • Weak • Partially dissociates • Alkaline • Another term for basic • Amphoteric • A substance that can act as both an acid and a base
