  1. Normal ending ____-ide ____-ate ____-ite Acid name is… hydro-___-ic acid _____-ic acid _____-ous acid Naming Acids

  2. Naming Acids • If the anion has oxygen in it, then it ends in -ate or -ite • change the suffix -ateto -ic acid(use no prefix) • Example: HNO3 Hydrogen and nitrate ions = Nitric acid • change the suffix -iteto -ous acid(use no prefix) • Example: HNO2 Hydrogen and nitrite ions = Nitrous acid

  3. Practice by naming these: • HF • H3P • H2SO4 • H2SO3 • HCN • H2CrO4

  4. Writing Acid Formulas – in reverse! • Hydrogen will always be listed first • The name will tell you the anion • Be sure the charges cancel out. • Starts with prefix hydro?- there is no oxygen, -ide ending for anion • no hydro?, -ate anioncomes from -ic, -ite anion comes from -ous

  5. Write formulas for these: • hydroiodic acid • acetic acid • carbonic acid • phosphorous acid • hydrobromic acid
