Chemistry – Dec 7, 2016 Objective – Acid Nomenclature Assignment: Finish the All Compounds Nomenclature Worksheet Agenda Acid Nomenclature Mixed Practice

Acid Nomenclature Overview Three nomenclature rules used for acids Based on the name of the anion that remains when the acidic H (s) are removed. Anions always end in either -ide, -ite, or -ate . This ending determines what naming rule is used. Ex: HCl Cl- Chloride -ide rule (Most are binary acids) Ex: H2SO4 SO42- Sulfate -ate rule (Oxoanions) Ex: HIO2 IO2- Iodite -ite rule (Oxoanions)

Binary Acids Acids are molecular compounds containing H that forms H+ ion and an anion when dissolved in water. Binary acids have only two elements, Hydrogen and a nonmetal. Named as hydrononmetalic acid Special cases: H2O = water H2O2 = hydrogen peroxide Name Formula hydrochloric acid HBr hydroiodic acid HCN hydrosulfuric acid H2Se hydrophosphoric acid HF

Oxyacids Acids formed with polyatomic ions containing oxygen Polyatomic ions end in either –ate or –ite -ate ion based acids are named using oxyanion–ic acid -ite ion based acids are named using oxyanion–ous acid Name Formula sulfuric acid H2CO3 hypochlorous acid HNO3 nitrous acid HBrO4 phosphoric acid HIO2

Summary of Inorganic Naming Rules Type Naming Rule Type 1 Binary ionic – one type of ion metal nonmetalide Type 2 Binary ionic – multiple ions form metal (roman numeral) nonmetalide Polyatomic ionic cation anion Molecular (two nonmetals) #prefixAelement #prefixBelementide Binary acids and –ide ion hydrononmetalic acid Oxyacid from –ate ion oxyanion–ic acid Oxyacid from –ite ion oxyanion–ous acid
