NOMENCLATURE Some general rules to help with nomenclature. Oxyacids (containing oxygen:) Anions: suffix -ous or -ic suffix -ite or -ate Examples: HNO 2 = Nitr ous Acid NO 2 - = Nitr ite HNO 3 = Nitri c Acid NO 3 - = Nitr ate H 2 SO 3 = Sulfur ous Acid SO 3 2- = Sulf ite H 2 SO 4 = Sulfur ic Acid SO 4 2- = Sulf ate Binary Compunds (Acids) Anions: prefix -hydro and suffix -ic suffix -ide Examples: HCl (aq) = Hydrochlor ic acid Cl - = Chlor ide HF (aq) = Hydrofluor ic acid F - = Fluor ide H 2 S (aq) = Hydrosulfur ic acid S 2 - = Sulf ide HCN (aq) = Hydrocyan ic aicd CN - = Cyan ide Note: In the two above cases charges on anions result from the number of acidic hydrogen atoms in an acid. (eg: SO 4 2- in H 2 SO 4 ). Binary Compounds (containing H and another non-metal): HF (g) = Hydrogen Fluoride HCl (g) = Hydrogen Chloride H 2 S (g) = Hydrogen Sulphide H 2 O = Hydrogen oxide (more commonly known as water!) Binary Compounds (2 different non-metals other than H): Note: Use the prefixes mono, di, tri, tetra for 1, 2, 3, 4 etc.
