3. First the easy stuff…Bases and their names!
Bases contain an OH group
If an OH group is present it will be clearly indicated: e.g. NaOH, Ca(OH)2
Also notice that bases have a metal (or positive ion such as NH4+ at their beginning)
Bases are named like other ionic compounds:
Cation is named first, followed by the polyatomic ion
Ca(OH)2
CuOH
aluminum hydroxide
ammonium hydroxide

4. What is an Acid?
There are many different definitions of an acid. We will be working with the simplest definition.
ACID – is a H+ (hydronium ion) donor.
This means that our acids will begin with the element “H”

5. Naming Acids
All acids are named by FIRST identifying the ANION present
Ignore the NUMBER of “H” atoms in the formula – concentrate on identifying the anion.

6. Naming Acids There are three basic rules to remember
Anion Name Acid Name
- ide Hydro ic Acid
-ate ic Acid
-ite ous Acid

7. Try a Few Acid Anion Acid Name HCl Cl- Chloride Hydrochloric Acid
H3PO4 PO43- Phosphate Phosphoric Acid
H2SO3 SO32- Sulfite Sulfurous Acid

8. Rules for Naming Acids – if the anion contains oxygen
The suffix –ic is added to the root name if the anion name ends in –ate.
Examples:
HNO3 Nitric acid
H2SO4 Sulfuric acid
HC2H3O2 Acetic acid
The suffix –ous is added to the root name if the anion name ends in –ite.
HNO2 Nitrous acid
H2SO3 Sulfurous acid
HClO2 Chlorous acid

9. Oxy-acid naming rules

10. Naming Acids- Examples
Acid Anion Acid Name
HClO ClO- HypoChlorite Hypochlorous Acid
H3PO5 PO53- PerPhosphate Perphosphoric Acid
The –ate and –ite ending of the anion still dictate how the acid will be named

12. Writing Acids This process is just the opposite of naming.
Identify the anion
Write the anion (including its charge)
The charge on the anion tell you how many “H+” atoms to add
Remove all charges

13. Writing Acids Name Anion Acid Formula Hydrobromic acid Br- HBr
Sulfuric acid SO42- H2SO4
Periodic acid IO4- HIO4
Phosphorous acid PO H3PO3
