Example:1. Define the chemical name of N2O3
Answer:N2O3
So, N2O3 has compound’s name:

Polyatomic Compound Nomenclature
Nomenclature of Polyatomic Salt and Base Compounds
•Polyatomic salt compounds
•Polyatomic base compounds
Cation + Anion
Metallic name + Hydroxide
Example: Na2CO3
Cation(metallic element) : Na+ (sodium)Anion (polyatomic ion) : CO3
2- (Carbonate)Compound name :Sodium Carbonate (not disodium carbonate)Indonesian : Natrium Karbonat
Ca(OH)2
Metal name : Ca (calcium)Compound name :Calcium Hydroxide (not calcium dihydroxide)Indonesian : Kalsium hidroksida
The element has 4 anionDefine the chemical name of NaClO,
NaClO2, NaClO3 and NaClO4
Answer: NaClO = Sodium HypochloriteIndonesian = Natrium hipoklorit NaClO2= Sodium Chlorite Indonesian = Natrium Klorit NaClO3 = Sodium ChlorateIndonesian = Natrium Klorat NaClO4 = Sodium Perchlorate
Indonesian = Natrium Perklorat
Nomenclature of Polyatomic Acid Compounds
•The nomenclature of polyatomic acid comounds (oxy acid compound) is similar with binary acid
•that is by defining the polyatomic anion then the H elements (acid).
1. For the element has 1 anion :
2. For the element has 2 anion :Polyatomic anion name + suffix -
ous / -ic + acid
Polyatomic anion name + suffix –ic + acid
Nomenclature of Polyatomic Acid Compounds3. For the element has 4 anion :a. First (Lowest) cation
b. Second cation
c. Third cation
d. Fourth (Highest) cation
Prefix Hypo- + Polyatomic anion name + suffix –ous + acid
Polyatomic anion name + suffix –ous + acid
Polyatomic anion name + suffix -ic + acid
Prefix Per- + Polyatomic anion name + suffix -ic + acid
Example:
1. Define the chemical name of H2CO3
Answer:H2CO3
Polyatomic Anion : CO32- (carbonate)
Compound name : Carbonic acidIndonesian : Asam karbonat
Example:
2. Define the chemical name of H2SO3 and H2SO4
Answer:H2SO3
Polyatomic Anion : SO32- (sulfite)
Compound name : Sulfurous acidIndonesian : Asam Sulfit H2SO4
Polyatomic anion : H2SO42- (sulfate)
Compound name : Sulfuric acidIndonesian : Asam Sulfat
Example:3. Define the chemical name of HClO,
HClO2, HClO3 and HClO4
Answer: HClO = Hypochlorous acidIndonesian = Asam hipoklorit HClO2= Chlorous acidIndonesian = Asam Klorit HClO3 = Chloric acidIndonesian = Asam Klorat HClO4 = Perchloric acid
Indonesian = Asam Perklorat
