The Rules for Naming and Formula Writing

2. Naming an Acid
Consider the acid “HX” where H is hydrogen and X is the anion.
RULE #1
When name of anion (X) ends in “ide”
Acid name begins with “hydro”
Followed by stem of anion
Followed by “ic acid”
Example: HCl

3. Naming an Acid
Consider the acid “HX” where H is hydrogen and X is the anion.
RULE #2
When name of anion (X) ends in “ite”
Name begins with stem of anion
Followed by “ous acid”
Example: HNO2

4. Naming an Acid
Consider the acid “HX” where H is hydrogen and X is the anion.
RULE #3
When name of anion (X) ends in “ate”
Name begins with stem of anion
Followed by “ic acid”
Example: HClO3

5. Practice Naming!
You try:
H2SO4
HBr
H2SO3
H3PO4
HClO
HClO4

6. Naming Bases
Name bases exactly like you would any other ionic compound.
Example:
NaOH = sodium hydroxide
