This comprehensive guide focuses on the naming conventions for both acids and bases in chemistry. Understand the differences between binary acids, which contain two different elements and start with the prefix "hydro-", and ternary acids, or oxyacids, which include three elements, typically comprising hydrogen, oxygen, and another element. Learn how to properly name common acids like hydrochloric acid and sulfurous acid, along with bases such as magnesium hydroxide and sodium hydroxide. A valuable resource for mastering chemical nomenclature.

Naming Acids • Binary acids • Contains 2 different elements: H and another • Always has “hydro-” prefix • Root of other element’s name • Ending “-ic” • Examples: HI, H2S, HBr, HCl
Naming Acids • Ternary Acids - Oxyacids • Contains 3 different elements: H, O, and another • No prefix • Name of polyatomic ion • Ending “–ic” for “-ate” • “–ous” for “-ite” • Examples: HClO3, H3PO4, HNO2
Practice • H2SO3 • Sulfurous acid • HF • Hydrofluoric acid • H2Se • Hydroselenic acid • Perchloric acid • HClO4 • Carbonic acid • H2CO3 • Hydrobromic acid • HBr
Naming Bases • Use Ionic rules • Name the first element then the second • Mg(OH)2 Magnesium Hydroxide • Ca(OH)2 Calcium Hydroxide • Na(OH) Sodium Hydroxide
Naming Bases • Use Ionic rules • Name the first element then the second • Mg(OH)2 • Ca(OH)2 • Na(OH) Magnesium Hydroxide Calcium Hydroxide Sodium Hydroxide
