1. Minds On…
Provide the IUPAC and Classical Names for each of the following:
PbO2 SnSO4
FeS Cu3(PO4)2
Multivalents

2. Nomenclature: Part III
LG: I can name acids and bases

3. Binary Acids
Binary acids are composed of HYDROGEN and one other NON-METAL
Classical Naming Rules
Prefix ‘hydro’ and ‘ic’ ending are added to more electronegative atom
Formula
Classical Name
IUPAC Name
HF(aq)
Hydrofluoric Acid
Aqueous Hydrogen Fluoride
HCl(aq)
Hydrochloric Acid
Aqueous Hydrogen Chloride
H2S(aq)
Hydrosulfuric Acid
Aqueous Hydrogen Sulfide
Aq = dissolved in water
Named like ionic compounds

4. Oxyacids Oxyacids are a combination of hydrogen and oxyanions
IUPAC naming: aqueous hydrogen _oxyanion_
Ie. HClO3 = aqueous hydrogen chlorate
Classical Naming:
Name of Oxyanion
Name of Oxyacid
Example
per - ate
Per - ic
SO52-
-ate
-ic
SO42-
-ite
-ous
SO32-
hypo-ite
hypo - ous
SO22-
Just write name of acid in example

5. Oxyacid Formulas Treated like an ionic compound
Include enough hydrogens to balance the charge on oxyanion
Examples:
Carbonic Acid Hypochlorous Acid

6. Bases
Common bases include ionic hydroxides, carbonates, and bicarbonates, in solution (in solution = aqueous)
Examples:
KOH (potassium hydroxide)
CaCO3 (calcium carbonate)
NaHCO3 (sodium bicarbonate or sodium hydrogen carbonate)

7. What do you notice about all of the acid formulas?
Practice
Classify each compound as an acid or a base.
Name each compound.
For each acid include the IUPAC and Classical name.
Na2CO3
H2SO4
H3PO4
Ca(HCO3)2
LiOH
HClO
HNO3
What do you notice about all of the acid formulas?
