Oxyanion and Acid Nomenclature Rules
Zero Oxygen: ending is ide (e.g., Chloride). Corresponding binary acid uses prefix Hydro- and ending -ic Acid (e.g., Hydrochloric Acid).
Subtracted 2 Oxygens: ending is Hypo- -ite (e.g., Hypochlorite). Corresponding acid uses prefix Hypo- and ending -ous Acid (e.g., Hypochlorous Acid).
Subtracted 1 Oxygen: ending is -ite (e.g., Chlorite). Corresponding acid uses ending -ous Acid (e.g., Chlorous Acid).
Base Oxyanion: ending is -ate (e.g., Chlorate). Corresponding acid uses ending -ic Acid (e.g., Chloric Acid).
Added 1 Oxygen: ending is Per- -ate (e.g., Perchlorate). Corresponding acid uses prefix Per- and ending -ic Acid (e.g., Perchloric Acid).
