+6: Oxygen in oxyanions is assumed to have an oxidation state of -2; there are four such oxygen atoms, for a total of -8, and the SO4 anion has a charge of -2. This means that the sulfur atom must have an oxidation state of +6, because +6 added to - 8 = -2.

∙ 13y agoThe oxidation number of SO4 is -2. This is because oxygen typically has an oxidation number of -2, and there are four oxygen atoms in the sulfate ion (SO4).
In (NH4)2Ce(SO4)3, the oxidation number of Ce is +3. The oxidation number of ammonium (NH4) is +1, and the oxidation number of sulfate (SO4) is -2.
In the sulfate ion (SO4^2-), the oxidation number of sulfur (S) is +6, while the oxidation number of each of the four oxygen (O) atoms is -2.
This should be SO4-2 ion. sulfur shows +6 in this ion.
The oxidation number of oxygen (O) in SO4 (sulfate) is -2. Since there are four oxygen atoms in the sulfate ion (SO4), they collectively contribute -8 to the overall charge of the ion, which is -2.
The oxidation number of sulfur in H2SO4 is +6. This is because hydrogen has an oxidation number of +1 and oxygen has an oxidation number of -2, so by the rules of oxidation numbers, sulfur must have an oxidation number of +6 to balance the equation.

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.
The oxidation number of calcium (Ca) is +2. The overall charge of a sulfate ion (SO4) is -2. Therefore, in CaSO4, calcium has an oxidation number of +2 and sulfate has an oxidation number of -2.
The oxidation number of chromium (Cr) in Cr2(SO4)3 is +3. This is because the overall charge of the sulfate ion (SO4) is -2, and there are a total of 3 sulfate ions present in the compound, requiring the chromium to have an oxidation state of +3 to balance the charges.
The oxidation number of Co in CoSO4 is +2. This is because the oxidation number of oxygen is -2 and the overall charge of the sulfate ion (SO4) is -2, so the oxidation number of Co must be +2 to balance the charges.
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 for sulfur (S) in tin(IV) sulfate (Sn(SO4)2) is +6. This is because the overall charge of the sulfate ion (SO4) is -2, and there are two sulfate ions present in the compound, leading to a total charge of -4. The oxidation number of tin (Sn) in this compound is +4.
The new oxidation number for Cr2O7^2- is +6, for H is +1, for SO3^2- is +4, for Cr3+ is +3, for SO4^2- is +6, and for H2O is 0.
The oxidation number of Al in Al2(SO4)3 is +3 because each sulfate ion (SO4) has a charge of -2 and there are 3 sulfate ions, leading to a total charge of -6. In order for the compound to be neutral, the aluminum ions must have a total charge of +6, leading to an oxidation number of +3 for each aluminum ion.
