substances离子化合物命名离子化合物命名（Names of ionic compounds）CuSO4 5H2O copper(II)sulfate pentahydrate The number of cations and anions per formula need not be included in the compound name because anions have characteristic charges,and the charge of the cation has already been established by its name.There are as many cations and anions as needed to get a neutral compound with the lowest possible integral subscripts.第28页Nomenclature of inorganic substancesNaming Inorganic AcidsReplace the-ate ending of an anion with“-ic acid”or replace the-ite ending with“-ous acid.”If the anion ends in-ide,add the prefix hydro-and change the ending to“-ic acid.”第29页Naming Acid SaltsThe anions of acid salt are named with the word“hydrogen”placed before the name of the normal anion.HSO4-is the hydrogen sulfate ion.To denote two atoms,the prefix di-is used.HPO42-is the hydrogen phosphate ion,while H2PO4-is the dihydrogen phosphate ion.In an older naming system,the prefix bi-was used instead of the word hydrogen when one of two hydrogen atoms was replaced.Thus,HCO3-was called the bicarbonate ion instead of the more modern name,hydrogen carbonate ion.Nomenclature of inorganic substances第30页Nomenclature of inorganic substancesNaming HydratesSome stable ionic compounds are capable of bonding to a certain number of molecules of water per formula unit.Thus,copper(II)sulfate forms the stable CuSO45H2O,with five molecules of water per CuSO4 unit.This type of compound is called a hydrate.The name of the compound is the name of the anhydrous(without water)compound with a designation for the number of water molecules appended.Thus,CuSO45H2O is called copper(II)sulfate pentahydrate.The 5 multiples everything after it until the next centered dot or the end of the formula.Thus,included in CuSO45H2O are ten H atoms and nine O atoms(five from the water and four in the sulfate ion).第31页International Union Of Pure And Applied Chemistry-IUPAC 无机化学命名法IUPAC 推荐(Nomenclature of InorganicChemistry IUPACRecommendations)第32页IUPACNomenclature of Inorganic Chemistry,commonly referred to by chemists as the Red Book,is a collection of recommendations on inorganic chemical nomenclature published at irregular intervals by the International Union of Pure and Applied Chemistry(IUPAC).The last full edition was published in,in both paper and electronic versions.A revision of the Red Book was therefore initiated in 1998.This revised Red Book will supersede not only the 1990 Red Book but also,where appropriate,Nomenclature of Inorganic Chemistry II-Recommendations (Red Book II).One of the main changes from the old Red Book is the different organization of material,adopted to improve clarity.Overall,the emphasis on additive nomenclature(generalized from the classical nomenclature of coordination compounds)which was already apparent in the 1990 Red Book,is reinforced.The reader facing the problem of how to name a given compound or species may find help in several ways.A flowchart is provided which will in most cases guide the user to a section or chapter where rules can be found for generating at least one possible name.A more detailed subject index is also provided,as well as an extended guide to possible alternative names of a wide range of simple inorganic compounds.第33页Name the following compounds by the
