Oxygen in compounds "always" has an ON of -2. With four oxygens in one sulfate, this is so far a total of -8. However, there is also a 2- charge on the ion, so we subtract this from the total: -8 --2 = -8 + 2 = 6. Since sulphur is the only atom left, it must carry the whole of this charge, making its ON (and formal charge) +6.
S has an oxidation number of +6 in sulfate ion ( O is -2 the overall charge is -2 so S must be +6)
+6
+4
+6
Oxygen atoms are generally considered to have an oxidation number of -2 in all oxyanions such as sulfate.
+3 for Al and -2 for O is the oxidation number for Al2O3.
+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.
oxidation number of S is +6.It oxidize into SO4 ^-2
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.

Chromium is a useful element. It shows +2 in this compound.
This should be SO4-2 ion. sulfur shows +6 in this ion.
This should be SO4-2 ion. sulfur shows +6 in this ion.
SO4^2- has a net negative 2 charge.each O = 2-S = 6+
zn is equal to +2 and so4 is equal to -2. those are the oxidation numbers. dont worry its correct
Aluminium is a light metal. Al shows +3 in aluminium sulfate.
The sulfur in potash alum occurs in sulfate ions, which have the formula SO4-2. Since sulfur is less electronegative than oxygen, the oxygen has an oxidation number of -2; 4 atoms of oxygen give a total negative charge of -8, and the sulfur atom must have an oxidation number of +6 to match the -2 charge of the sulfate ion as a whole.
