  1. Acids and Bases Unit 6: Nomenclature - Part IV Mrs. Callender

  2. Lesson Essential Questions: How do I write a formulas for acids and bases? How do I name acids and bases?

  3. Ex. HCl Writing Common Names for Binary Acids. Acid Hydro chlor ic 1. It is an acid because it starts with hydrogen. 2. Since it is a binary acid it starts with the prefix hydro-. 3. Part of the anion name comes next. 4. Followed by the suffix –ic. 5. The word Acid is added to the end.

  4. Ex. HI Writing Common Names for Binary Acids. Acid ic Hydro iod 1. It is an acid because it starts with hydrogen. 2. Since it is a binary acid it starts with the prefix hydro-. 3. Part of the anion name comes next. 4. Followed by the suffix –ic. 5. The word Acid is added to the end.

  5. Ex. H3 PO4 Writing Common Names for Polyprotic Acids. Acid ic Phosphor 1. It is an acid because it starts with hydrogen. 2. It is a polyprotic acid because it contains a polyatomic ion. 3. Anion name is written first minus the suffix (-ate). 4. If it contains an –ate polyatomic ion then the anion gets the suffix –ic. 5. The word Acid is added to the end.

  6. Ex. H2SO3 Writing Common Names for Polyprotic Acids. Acid Sulfur ous 1. It is an acid because it starts with hydrogen. 2. It is a polyprotic acid because it contains a polyatomic ion. 3. Anion name is written first minus the suffix (-ite). 4. If it contains an –ite polyatomic ion then the anion gets the suffix –ous. 5. The word Acid is added to the end.

  7. Little Help Remembering… If we –ate something –icky it m-itekill –ous. Remember… this is only for polyprotic acids. Binary Acids get a hydro- prefix with an –ic suffix.

  8. Writing Acid Formulas. Ex.Hydroiodic Acid It is an acid so it’s going to start with hydrogen. 2. Write the anion with it’s charge and balance. +1-1= Net charge of zero which means it is balanced. I-1 H+1 HI

  9. Writing Polyprotic Acid Formulas Ex.Perchloric Acid Starts with hydrogen because it’s an acid. 2. Write the anion with it’s charge. -ic acid means it came from an –ate polyatomic ion. +1-1= Net charge of0which means it is balanced. H+1 ClO4-1 HClO4 Balanced

  10. Writing Polyprotic Acid Formulas Ex.Phosphorous Acid Starts with hydrogen because it’s an acid. 2. Write the anion with it’s charge. -ous acid means it came from an –ite polyatomic ion. +1-3= Net charge of -2 which means it is NOT balanced. H+1 PO3-3 H3PO3 Not Balanced

  11. Bases Bases contain –OH ions Ex. sodium hydroxide Write the symbol of the cation with its charge. 2. Write the anion with it’s charge.. +1-1= Net charge of -0 which means it is balanced. Na+1 OH-1 NaOH Balanced
