Acids and Bases: NamingAt the conclusion of our time together, you should be able to:

1. Name any acid or base 2. Determine if the acid is binary or

ternary (oxy-acid) and use the appropriate naming system

Naming Acids

Prefix

Hydro-

Stem or root of nonmetal

< NM >

Suffix

-ic acid

HCl Hydro

HI

HCl is a binary acid – hydrogen - nonmetal

chlor ic acid

H2S

Naming Acids (cont.)Ternary Acids (oxyacids):Contain “H”, “O” and one more element

To Name:Polyatomic ion “ate” “ic” + acid

Ex: HNO3 = Nitr-ate ic + acidNitric acid

HClO3 =

An easy way to remember which goes with which…

“In the cafeteria, you ATE something ICky”

Naming Acids (cont.)If the acid has one more oxygen than the root acid, the naming goes as follows:

To Name: Per + Polyatomic ion “ate” “ic” + acid

Ex: HNO4 = Per + Nitr-ate ic + acidPernitric acid

H2SO5 =

Naming Acids (cont.) If the acid has one less oxygen than the root acid, the naming goes as follows:

To Name: Polyatomic ion “ite” “ous” + acid

Ex: HNO2 = Nitr-ite ous + acidNitrous acid
