Warm-Up: Brainstorm • What is an acid? • What is a base?
Acids and Bases May 6th, 2013
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
Examples of an Acid • Battery Acid • Citrus juices • Stomach Acid • Vinegar
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
What is a base? • Bitter Taste • Feels slippery • Contains OH- ions • Bronstead-Lowry Proton acceptor [H+] • Arrhenius increases [OH-]
Examples of Bases • Soap • Dark Chocolate • Antacid • NaOH
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
