Acids and Bases

Acids

•All acids are formed by an ionic bond between hydrogen ion (metal) and

an anion (nonmetal) or

a polyatomic ion (nonmetal).

Depends on the types of ions in the acid.

Types of ions:Single ionsPolyatomic ions

Naming Acids

Hydrogen + Anion

“Hydro _____ ic Acid”

Naming Acids – Single Ions

Naming Acids – Single Ions

•HF (aq) = hydroflouric acid•HCl (aq) = Hydrochloric acid•HBr (aq) = hydrobromic acid•H2S (aq) = hydrosulfuric acid

Naming Acids – Polyatomic Ions

Hydrogen + Polyatomic Ion

Name of the polyatomic anion + -ic acid

Naming Acids – Polyatomic

•Example:HNO3

Nitrate Ion nitric acid

H2SO4

Sulfate Ion Sulfuric acid

Bases

•All bases are formed by an ionic bond betweencation (metal) and

hydroxide (OH-) ion

Naming Bases

Examples:

NaOH (aq) Sodium hydroxide

Ca(OH)2 (aq) Calcium hydroxide

Mg(OH)2 (aq) Magnesium hydroxide
