The oxidation number of sulfur in the bisulfate ion (HSO4-) is +6. Sulfur typically has an oxidation number of -2 in sulfates (SO4 2-) and gains an additional oxygen atom in bisulfate, hence the oxidation number of +6.
The oxidation number of sulfur in aluminum sulfate is +6. This is because each oxygen atom has an oxidation number of -2, and there are four oxygen atoms in the sulfate ion (SO4). The overall charge of the sulfate ion is -2, so the oxidation number of sulfur must be +6 to balance the charge.
For CaSO4 (calcium sulfate), the oxidation number of sulfur is +6. For SO4 (sulfate ion), the oxidation number of sulfur is +6. For SO2 (sulfur dioxide), the oxidation number of sulfur is +4. For SO3 (sulfur trioxide), the oxidation number of sulfur is +6.
This should be SO4-2 ion. sulfur shows +6 in this ion.
The oxidation number of the polyatomic ion sulfate (SO4) is -2. Each oxygen atom contributes -2, and since sulfate has a charge of -2, the single sulfur atom must have an oxidation number of +6 to balance the charges.
This should be SO4-2 ion. sulfur shows +6 in this ion.

In oxygen containing anions that also include a less electronegative element, oxygen is taken to have an oxidation number of -2. A sulfate ion has a charge of -2. The four oxygen atoms of a sulfate ion have a total charge of 4 X -2 or -8; therefore, the oxygen atom must have an oxidation number of +6 to yield the correct value for the charge of the sulfate ions.
In CuSO4, the oxidation number of copper (Cu) is +2, and the oxidation number of sulfur (S) is +6. This is because the overall charge of the sulfate ion (SO4) is -2.
In an iodometric titration experiment, the oxidation number of sulfur changes from -2 in the thiosulfate ion (S2O32-) to +4 in the sulfate ion (SO42-) as sulfur gains oxygen atoms. This change indicates the transfer of electrons and oxidation of sulfur during the reaction.
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.
There is no oxidation number for compounds, only the elements within compounds. The charge of SO4 (sulfate) is 2-. The oxidation number of each oxygen is 2-. The oxidation number of the sulfur in this compound is 6+.
To find the oxidation number or charge of a polyatomic ion, consider the known charges of the individual atoms within the ion. For example, in the sulfate ion (SO4)2-, oxygen typically has an oxidation number of -2, and sulfur would then have an oxidation number to balance the charge of the ion. The sum of the oxidation numbers of all the atoms in the ion should equal the overall charge of the 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.
