Calcium sulfite, or calcium sulphite, is a chemical compound which is the salt of calcium cation and sulfite anion with the molecular formula CaSO3. As a food additive it is used as a preservative under the E number E226. It is commonly used in preserving wine, cider, fruit juice, canned fruit and vegetables.Calcium sulphiteE226Sulfurous acid calcium saltSulfurous Acid, Calcium Salt (1:1)CaO3S120.141119.919405711calcium sulfitecalcium sulfite10257-55-3[Ca++].[O-]S([O-])=OInChI=1S/Ca.H2O3S/c;1-4(2)3/h;(H2,1,2,3)/q+2;/p-2GBAOBIBJACZTNA-UHFFFAOYSA-L belongs to the class of inorganic compounds known as alkaline earth metal sulfites. These are inorganic compounds in which the largest oxoanion is sulfite, and in which the heaviest atom not in an oxoanion is an alkaline earth metal.Alkaline earth metal sulfitesInorganic compoundsMixed metal/non-metal compoundsAlkaline earth metal oxoanionic compoundsAlkaline earth metal sulfitesInorganic calcium saltsInorganic oxidesAlkaline earth metal sulfiteInorganic calcium saltInorganic oxideInorganic saltmelting_point600 °C, 873 K, 1112 °Flogp-1.2pka_strongest_acidic-3.7iupaccalcium sulfiteaverage_mass120.141mono_mass119.919405711smiles[Ca++].[O-]S([O-])=OformulaCaO3SinchiInChI=1S/Ca.H2O3S/c;1-4(2)3/h;(H2,1,2,3)/q+2;/p-2inchikeyGBAOBIBJACZTNA-UHFFFAOYSA-Lpolar_surface_area63.19refractivity10.08polarizability5.1rotatable_bond_count0acceptor_count3donor_count0physiological_charge-1formal_charge0Specdb::MsMs1271674Specdb::MsMs1271675Specdb::MsMs1271676
