  1. Naming Acids

  2. Remember • Polyatomic Ions • Atoms that are grouped with a charge. • Must have at least two different atoms. Suffix “ate” • Nitrate: NO3 - • Carbonate: CO3 2- • Sulfate: SO4 2- • Phosphate: PO4 3- • Chromate: CrO4 2- • Chlorate: ClO3 - Suffix “ite” • Nitrite: NO2 - • Sulfite: SO3 2- • Phosphite: PO3 3-

  3. Remember • Ammonium (NH4 +) is the only + polyatomic ion you need to know. • Phosphate (PO4 3-) is the only 3- polyatomic ion you need to know.

  4. Remember “Per-X-ate” loses oxygen “X-ate” loses oxygen “X-ite” • X represents the stem word for an ion loses oxygen “hypo-X-ite”

  5. Hints to Naming Acids • “Per-_____-ate” to “Per-_____-icAcid” • “_____-ate” to “_____-ic Acid” • “_____-ite” to “_____-ous Acid” • “Hypo-_____-ite” to “hypo-_____-ous Acid” • “_____-ide” to “hydro-_____-ic Acid”

  6. Hints to Naming Acids • If you have a MONATOMIC anion: • Add the prefix Hydro- • Add the suffix –ic • Add the word “Acid” to the end • “_____-ide” to “Hyrdo-_____-ic Acid”
