Naming Acids And Bases
Day 3
Naming Acids
 Acids usually have H as the cation
HCl
 Acids are named depending on whether they are oxyacids (ternary acids) or
non-oxyacids (binary acids)
 Oxyacids= acids with Oxygen in their formula
 H₂SO₄
HNO₂
H₃PO₃
 Non-oxyacids= acids without Oxygen in their formula
 HCl
HBr
Naming Oxyacids
 Drop “Hydrogen”
 -ate becomes –ic
 Something you –ate was -ic
 -ite becomes –ous
 Wh-ite h-ouse
 H₂SO₄
 Hydrogen Sulfate→Sulfuric acid
 HNO₂
 Hydrogen Nitrite→Nitrous acid
 My doctor said I have ate-ic-iteous!
Naming Non-Oxyacids
 “Hydrogen” becomes “Hydro-”
 -ide becomes –ic
 S-ide k-ick
 An oxyacid –ate something that
made it s-ick in the wh-ite h-ouse.
 Non-oxyacids are just s-ide k-icks
 HCl
 Hydrogen Chloride→Hydrochloric
acid
 HBr
 Hydrogen Bromide→Hydrobromic
acid
 HF
 Hydrogen Fluoride→Hydrofluoric
acid
Practice Makes Perfect!
 Name the following compounds using the naming rules for acids:
 1. HF
 2. HI
 3. HNO₃
 4. H₂SO₃
Answers
 1. HF
Hydrofluoric acid
 2. HI
Hydroiodic acid
 3. HNO₃ Nitric acid
 4. H₂SO₄ Sulfuric acid
Naming Bases Review
 Bases have OH⁻ as the anion
NaOH
 Say element name and then “hydroxide”
 KOH
Potassium Hydroxide
 Ca(OH)₂
Calcium Hydroxide
 Al(OH)₃
Aluminum Hydroxide
Practice!
 Name the following compounds using the naming rules for bases:
 1. Mg(OH)₂
 2. Fe(OH)₃
 3. NH₄(OH)
 4. Ba(OH)₂
Answers
 1. Mg(OH)₂
Magnesium Hydroxide
 2. Fe(OH)₃
Iron (III) Hydroxide
 3. NH₄(OH)
Ammonium Hydroxide
 4. Ba(OH)₂
Barium Hydroxide
Now Let’s Go Backwards!
 Given the following names, write the correct formula:
 1. Copper (II) Hydroxide
 2. Hydrofluoric acid
 3. Phosphoric acid
 4. Sodium hydroxide
Answers
 1. Copper (II) Hydroxide
Cu(OH)₂
 2. Hydrofluoric acid
HF
 3. Phosphoric acid
H₃PO₄
 4. Sodium Hydroxide
NaOH
You know I’m all about that base!
