Oxygen atoms are generally considered to have an oxidation number of -2 in all oxyanions such as sulfate.
This should be SO4-2 ion. sulfur shows +6 in this ion.
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.
The oxidation number of oxygen (O) in most compounds, including sulfate (SO4), is typically -2. In Na2SO4, sodium (Na) has an oxidation number of +1. To calculate the oxidation number of oxygen in the compound, you would use the equation: 2(oxidation number of Na) + oxidation number of S + 4(oxidation number of O) = 0. By plugging in the known values, you can solve for the oxidation number of oxygen in Na2SO4.
Since the SO4-2 ions have two negative charges and oxygen atoms in almost all compounds have two negative charges each, the sulfur atoms have an oxidation number of -2 -4(-2) = +6.
This should be SO4-2 ion. sulfur shows +6 in this ion.

+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.
+3 for Al and -2 for O is the oxidation number for Al2O3.
Each of the hydrogen atoms in H2 has an oxidation number of 0.
SO4^2- has a net negative 2 charge.each O = 2-S = 6+
The oxidation number of Pb in PbSO4 is +2. This is because the oxidation number of oxygen is typically -2, and the overall charge of the sulfate ion (SO4) is -2, so the oxidation number of Pb must be +2 to balance the charges in the compound.
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.
