Naming Acids
Acids are compounds, usually ionic,
which have H+ as the cation

2. Inorganic Acids
Can be grouped into two types
Binary and Oxoacids

3. Binary Acids Contain only two different elements
One of them is H+ and the other is an anion
To name them:
1) Take the anion root word, put hydro in front of it
2) Change the ending from -ide to -ic Acid
Example: HCl is H+ with a chloride Cl- ion. The name is Hydrochloric Acid
HBr Hydro + brom ic Acid

4. Oxoacids Acids whose anions are polyatomic anions that contain oxygen.
H+ is still the cation.
To name them:
Change the –ate ending of the anion to –ic Acid
OR change the –ite ending of the anion to –ous Acid
Examples:
HNO3 This is H+ with the nitrate (NO3-) ion Nitric Acid
HNO2 This is H+ with the nitrite (NO2-) ion
Nitrous Acid

5. Organic Acids Contain carbon
Except for carbonic acid, which is considered inorganic.
Their naming system is basically the same as the oxoacids
The one that you need to know is Acetic Acid (vinegar):
CH3CO2H or sometimes written CH3COOH.
This is a H+ with the acetate (CH3CO2-) ion.
