1. Naming Chemical Compounds
Ionic Compounds

2. Ionic Compounds Monatomic cations Mono means 1
Cations are + metal ions
Remember

3. Ionic Compounds Monatomic anions Mono means 1
Anions are – non-metal ions

4. Naming Ionic Compounds
I didn’t
Catch your name.
Name the cation (monatomic or polyatomic), add Roman Numeral if a transition metal
Add the suffix –ide to the anion if monatomic. Name the Polyatomic.
Bond,
Ionic Bond

5. Ionic Compounds Polyatomic ions Poly- means many or more than one
These are two or more atoms bonded together with an overall charge
Most polyatomic ions are negative

6. Naming Compounds -ite GOT –ate
-ate endings have one more oxygen (O) than –ite endings.
NO2-1 nitrite NO3-1 nitrate
SO3-1 sulfite SO4-1 sulfate

7. Hydrates (Water)
Hydrates simply means that one or more water molecules are attached
Name the ionic compound
Use prefixes to tag the # of water molecules

8. Practice Naming Hydrates
CuSO4 * H2O
Copper (II) Sulfate Monohydrate
Na2CO3 * 6H2O
Sodium Carbonate Hexahydrate
Ca3(PO4)2 * 2H2O

9. Naming Acids
All acids are characterized by beginning their molecular formula with the hydrogen (H) atom.
HCl, H2SO4, HNO3, HI, HF, HC2H3O2
That is because a H+ is given off when it is dissolved (disassociates) in water.

10. Naming Acids
We will use the prefix hydro- and suffic –ic if the anion ends in –ide
HCl hydrogen chloride would be hydrochloric acid HF HI
HBr

11. Naming Acids Acids that end with the suffix –ate.
Replace with the –ic suffix
HNO3 hydrogen nitrate
Nitric Acid
Just remember, I –ate something –ic(y).

12. Naming Acids Acids that end with the suffix –ite.
Replace with the suffix –ous.
HClO2 hydrogen chlorite
Chlorous acid
–ite is said by –ous.

13. Let’s Practice
HCl
H2SO4
HNO3
HNO2
HC2H3O2
H2CO3 HF
