what is an acid
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
Examples of an Acid
  • Battery Acid
  • Citrus juices
  • Stomach Acid
  • Vinegar
acid terminology
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
What is a base?
  • Bitter Taste
  • Feels slippery
  • Contains OH- ions
  • Bronstead-Lowry  Proton acceptor [H+]
  • Arrhenius  increases [OH-]
examples of bases
Examples of Bases
  • Soap
  • Dark Chocolate
  • Antacid
  • NaOH
base terminology
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
