SO32- is Sulfite.
The correct name for the SO32- polyatomic ion is sulfite ion.
Sulfite ion
The sulfate ion is SO42 -. The oxidation state of the sulfur is +6 (work it out!); therefore, the ion is more properly named the sulfate(VI) ion. The sulfite ion is SO32-. The oxidation state of the sulfur is +4.
So^2+ (thionyl ions) & so3^2- (sulphite ions)
The sulphide (or sulfide) ion is similar to a sulfur atom except for 2 additional electrons, so its formula is S2-. In older references you might find this formula written S-2 or S--.
The correct name for the SO32- polyatomic ion is sulfite ion.
NO such molecule as 'So32'. If you mean 'SO3^(2-)' this is the sulphite anion. NB There is no element with the initials 'So'. or no molecule with '32' oxygen atoms to one sulphur atom.
Sulfite ion
SO3-- or SO32-
it is S2- ,while sulphite ion is SO32-
The zinc ion (Zn2+) and sulfite ion (SO32-) create the ionic compound of Zinc Sulfite, or ZnSO3.
The sulfite ion is SO32- It is not to be confused with sulfate, SO42-
Sulfite anion is the chemical name for SO32-
The oxidation number of sulfur in SO32 is +4. This is because oxygen always has an oxidation number of -2, so the sum of the oxidation numbers in the compound must equal the charge of the ion, which is -2 for SO32.
HSO3- is a stronger base than SO32- because it can accept a proton (H+) more readily. The presence of the H+ ion in HSO3- makes it more capable of accepting another proton compared to SO32-.
The sulfate ion is SO42 -. The oxidation state of the sulfur is +6 (work it out!); therefore, the ion is more properly named the sulfate(VI) ion. The sulfite ion is SO32-. The oxidation state of the sulfur is +4.
