1. Naming Acids And Bases
Day 3

2. 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

3. Naming Oxyacids My doctor said I have ate-ic-ite- ous! Drop “Hydrogen”
-ate becomes –ic
Something you –ate was -ic
-ite becomes –ous
Wh-ite h-ouse
My doctor said I have ate-ic-ite- ous!
H₂SO₄
Hydrogen Sulfate→Sulfuric acid
HNO₂
Hydrogen Nitrite→Nitrous acid

4. 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

5. Practice Makes Perfect!
Name the following compounds using the naming rules for acids:
1. HF
2. HI
3. HNO₃
4. H₂SO₃

6. Answers 1. HF Hydrofluoric acid 2. HI Hydroiodic acid
3. HNO₃ Nitric acid
4. H₂SO₄ Sulfuric acid

7. 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

8. 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

9. 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

10. 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

11. Answers 1. Copper (II) Hydroxide Cu(OH)₂ 2. Hydrofluoric acid HF
3. Phosphoric acid H₃PO₄
4. Sodium Hydroxide NaOH

12. You know I’m all about that base!

13. Study Time!
Take the next few minutes to review for your test or ask questions.
