					Acid Nomenclature
A water solution of a compound of hydrogen bonded to a halogen takes the following form. These are called binary acids Compound Hydrogen fluoride Hydrogen chloride Hydrogen bromide Hydrogen iodide Formula HF HCl HBr HI Water Solution Hydrofluoric acid Hydrochloric acid Hydrobromic acid Hydroiodic acid

Hydrogen forms compounds with polyatomic ions to form OXYACIDS. As is the case with oxygenated polyatomic forms as they bond with metals, the names change as the number of oxygen atoms present in the ion. These are called ternary acids Remember, the suffix –ite denotes one less oxygen than the –ate form. The prefix hypoand the suffix –ite together on the same form denote two less oxygens than the –ate form. The prefix per- denotes one more oxygen than the –ate form. The names of the acid forms are taken from the traditional system with the suffixes –ous and –ic.
