20、e 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.Nomenclature of inorganic substancesNaming Inorganic AcidsReplace the-ate ending of an anion with“-ic acid”or replace

21、the-ite ending with“-ous acid.”If the anion ends in-ide,add the prefix hydro-and change the ending to“-ic acid.”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 u

22、sed.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 io

23、n.Nomenclature of inorganic substancesNomenclature 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 ty

24、pe 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

25、 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).International Union Of Pure And Applied Chemistry-IUPAC 无机化学命名法无机化学命名法IUPAC 2005年推荐(Nomenclature of InorganicChemistry IUPACRecommendations 2005)IUPACNomenclature of Inorg
