Acids and Bases

All acids are formed by an ionic bond between hydrogen ion (metal) and an anion (nonmetal) or a polyatomic ion (nonmetal).

Naming Acids Depends on the types of ions in the acid. Types of ions: Single ions Polyatomic ions

Naming Acids – Single Ions Hydrogen + Anion  “Hydro _____ ic Acid”

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

All bases are formed by an ionic bond between cation (metal) and hydroxide (OH-) ion

NaOH (aq)  Sodium hydroxide Ca(OH)2 (aq)  Calcium hydroxide Naming Bases Examples: NaOH (aq)  Sodium hydroxide Ca(OH)2 (aq)  Calcium hydroxide Mg(OH)2 (aq)  Magnesium hydroxide
