  1. Acids and Bases Names and Formulas

  2. Binary Acids • Binary acids are made of two ions. The first ion (cation) is always H+. Change hydrogen to hydro- Replace the ending, –ide, on the second ion (anion) with –ic.

  3. Naming Binary Acids Example: Formula: HCl H+ hydrogen = hydro- Cl- chloride = chloric hydro-chlor-ic hydrochloric acid

  4. Writing Binary Inorganic Acid Formulas • The first ion (cation) is always hydrogen, H+. • The second ion (anion) is usually from Group VII A (halogen). • Exception: Group VIA - S (sulfur).

  5. Binary Acid Formula Example: hydroiodic acid cationanion H+ I- Formula: HI

  6. Oxyacids Oxyacids contain hydrogen, oxygen and a third element (usually a nonmetal). The first ion (cation) is always H+ The second ion (anion) is a polyatomic ion.

  7. Naming Oxyacids I • If the anion name ends in –ate, the suffix –ic is added to the root name.

  8. Example: HNO3 H+ NO3- NO3- , is the anion. nitrate, Replace –ate with –ic nitric Add “acid” = nitric acid HNO3

  9. Naming Oxyacid Acids II • If the anion name ends in –ite, the suffix –ous is added to the root name.

  10. One less oxygen? HNO2 NO2- , is the anion. nitrite, Replace –ite with –ous = nitrous Add “acid” = nitrous acid HNO2

  11. Try These • H2SO4 • H2SO3

  12. Example: H2SO4 • SO42- = sulfate ion S = sulfur • Replace –ate with –ic = sulfuric Add “acid” = sulfuric acid H2SO4

  13. One less oxygen? H2SO3 SO32- = sulfite ion S = sulfur Replace –ite with –ous = sulfurous Add “acid” = sulfurous acid H2SO3

  14. Writing Oxyacid Formulas • The first ion (cation) is always hydrogen, H+. • The second ion (anion) is a polyatomic ion.

  15. Writing an Oxyacid Formula Example: phosphoric acid cationanion H+ PO43- Formula = H3PO4

  16. Naming Inorganic Bases Don’t change the name of the lst ion. The last name of a base will always be hydroxide. Examples: NaOH = sodium hydroxide (NH4)OH = ammonium hydroxide

  17. Writing Formula for an Inorganic Base Example: zinc hydroxide cationanion Zn2+ OH- Formula: Zn(OH)2

  18. Name the Acids Put in Classwork/Homework Notebook 1. HF 5. HClO3 2. HBr 6. HIO4 3. HC2H3O2 7. HIO3 4. H2S 8. HIO2

  19. Write formulas for the acids Put in your Classwork/Homework Notebook. • Hydrosulfuric acid • Carbonic acid • Hypochlorous acid • Hypoiodous acidd • Perchloric • Chlorous acid

  20. Naming Bases Put in Classwork/Homework Notebook 1. LiOH 6. Ba(OH)2 2. KOH 7. Al(OH)3 3. RbOH 8. Fe(OH)3 4. Ca(OH)2 9. CsOH 5. Sr(OH)2

  21. Write Formulas for Bases Put in your Classwork/Homework Notebook. • Chromium (III) hydroxide • Mercury(II) hydroxide • Nickel (II) hydroxide • Tin (II) hydroxide • Cobalt (III) hydroxide
