Best Answer

If you mean SO3^-2 (the sulfite anion), then S has an oxidation number of 4+, since each O atom is 2-. In sulfur trioxide, SO3, the S atom has an oxidation number of 6+.

What is the oxidation state of an individual sulfur atom in SO32 and minus?

The oxidation state of an individual sulfur atom in (SO3)2- is 4.


What is the oxidation state of S in 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.

Is sulfur dioxide a sulfite?

No. A sulfite is a compound containing the sulfite ion, SO32-. Sulfur dioxide is the anhydride of sulfurous acid. Sulfites are salts of sulfurous acid.

What is the formula SO3?

SO3 is the chemical formula of sulfur trioxide (sulfur-IV oxide). It is a very hygroscopic, strongly acid forming oxide (extremely corrosive in humid air).


Why is the valency of sulphate and sulphite same?

Coincidence! the oxidation number of sulfur in sufate is +6, in sulfite is +4. Sulfate is SO42-, sulfite is SO32- Personally I do not like using the word valency in this context, valency usually refers to elements- and is the number of bonds that an elemnt can form to other elemnts- it is an old term. In the context of ions charge seems to be a better word.


Is sulfur dioxide the same as sulfite?

No, sulfur dioxide is a gas with the formula SO2 Sulfite is an ion with the formula (SO32-). It occurs along side some sort of positive ion to balance its negative charge. These compounds, called sulfites, can form when sulfur dioxide, an acidic oxide, reacts with basic oxides. Most metal oxides are basic.
