Unformatted text preview: Anion with lower # O atoms has ite suffix, one with higher # of oxygen atoms is ate . E.g. sulfite and sulfate Polyatomic Anions (b) When there are more than 2 in a series of oxyanions, Then use prefix hypo for less than and per for greater than Naming Compounds (a) Naming Compounds (b) Naming Acids (a) Acids produce Protons in water Sulfurous acid Sulfuric acid HCl Hydrochloric acid HBr Hydrobromic acid Naming Acids (b) Chlorine containing Acids Acid Anion Name Acid Name HClO Hypochlorite Hypochlorous Acid HClO 2 Chlorite Chlorous Acid HClO 3 Chlorate Chloric Acid HClO 4 Perchlorate Perchloric Acid Naming Acids (c)...
