There are as many cations and anions as needed to get a neutral compound with the lowest possible integral subscripts.,Nomenclature of inorganic substances,Naming Inorganic Acids Replace 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.”,Naming Acid Salts The 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,Nomenclature of inorganic substances,Naming Hydrates Some 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).,International Union Of Pure And Applied Chemistry -IUPAC,无机化学命名法 IUPAC 2005年推荐 (Nomenclature of Inorganic Chemistry IUPAC Recommendations 2005),IUPAC,Nomenclature 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 2005, 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 2000 (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 emph
