Naming acids

Acids nomenclature

How to recognize an acid


*You can recognize an acid by the fact that it's formula starts with H

- HCl -HNO3 -H2SO4

Some acids formula don't start with H

Like CH3COOH = HC2H3O2


*H2O is not considered an acid

Recognize polyatomic ions

Binary acids

1) prefix "hydro" is used

2) root of the anion is used

3) suffix "ic" is used

4) the word "acid" is used as the second word in the name
