Information: - Bisulfite ion ( IUPAC - recommended nomenclature : hydrogen sulfite ) is the ion HSO3 . Salts containing the HSO3 ion are termed bisulfites also known as sulfite lyes . For example , sodium bisulfite is NaHSO3 . - The sulfate or sulphate (see spelling differences) ion is a polyatomic anion with the empirical formula . Sulfate is the spelling recommended by IUPAC, but sulphate is used in British English. Salts, acid derivatives, and peroxides of sulfate are widely used in industry. Sulfates occur widely in everyday life. Sulfates are salts of sulfuric acid and many are prepared from that acid. - An ion is an atom or a molecule in which the total number of electrons is not equal to the total number of protons, giving the atom or molecule a net positive or negative electrical charge. Ions can be created, by either chemical or physical means, via ionization. - Sulfites or sulphites are compounds that contain the sulfite ion (or the sulfate(IV) ion, from its correct systematic name), . The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, its salts are widely used. - Sulfurous acid (also sulphurous acid) is the chemical compound with the formula HSO. There is no evidence that sulfurous acid exists in solution, but the molecule has been detected in the gas phase. The conjugate bases of this elusive acid are, however, common anions, bisulfite (or hydrogen sulfite) and sulfite. Sulfurous acid is an intermediate species in the formation of acid rain from sulfur dioxide. Given the information above, choose from the list below the object entity that exhibits the relation 'subclass of' with the subject 'bisulfite'. Choices: - acid - anion - atom - base - british english - chemical compound - english - formation - formula - hydrogen - ion - nomenclature - phase - solution
**Answer**
chemical compound
