+6 for sulfur in sulfates
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.
This is a ionic compound too. Sulfur shows +6 in sulfate 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.
As SO42- has an overall -2 charge, The Oxygen has a -2 oxidation state, so to balance and give an overall -2 charge, the Sulfur has to have a +6 oxidation state. (-2 x 4) + (s) = -2 s = +6
Magnesium forms cations with a charge of +2, and oxygen in oxyacids is assigned a formal charge or oxidation state of -2. There are four oxygen atoms in each sulfate ion, so that the total charge from oxygen is -8. This means that the oxidation number of sulfur must be +6, so that the total charges will sum to zero, as required for a compound.

Sufuric acid is a molecule: it is not an element. As a whole it has oxidation number 0. With six covalent bonds with four different oxygen atoms, sulfur has +6 oxidation number. Hydrogen and oxygen have +1 and -2 oxidation numbers respectively.
Aluminum Sulfate is Al2 SO4 (aluminum, sulfur, and oxygen)
There are s8 sulfur molecules. It shows 0 oxidation number.
Aluminum sulfate Al2(SO4)3 will form when aluminum reacts with sulfur in the presence of oxygen.
This is the thiosulfate ion. Sulfur shows +6 oxidation number.
Sulfur is one of the constituents of many proteins, vitamins and hormones. It recycles as in other biogeochemical cycles.The essential steps of the sulfur cycle are:Mineralization of organic sulfur to the inorganic form, hydrogen sulfide: (H2S).Oxidation of sulfide and elemental sulfur (S) and related compounds to sulfate (SO42-).Reduction of sulfate to sulfide.Microbial immobilization of the sulfur compounds and subsequent incorporation into the organic form of sulfur.These are often termed as follows: Assimilative sulfate reduction (see also sulfur assimilation) in which sulfate (SO42-) is reduced to organic sulfhydryl (otherwise known as thiol) groups (R-SH) by plants, fungi and various prokaryotes. The oxidation states of sulfur are +6 in sulfate and -2 in R-SH. Desulfuration in which organic molecules containing sulfur can be desulfurated, producing hydrogen sulfide gas (H2S), oxidation state = -2. Note the similarity to deamination. Oxidation of hydrogen sulfide produces elemental sulfur (So), oxidation state = 0. This reaction is done by the photosynthetic green and purple sulfur bacteria and some chemolithotrophs. Further oxidation of elemental sulfur by sulfur oxidizers produces sulfate. Dissimilative sulfur reduction in which elemental sulfur can be reduced to hydrogen sulfide. Dissimilative sulfate reduction in which sulfate reducers generate hydrogen sulfide from sulfate.Human impact on the sulfur cycle is primarily in the production of sulfur dioxide (SO2) from industry (e.g. burning coal) and the internal combustion engine. Sulfur dioxide can precipitate onto surfaces where it can be oxidized to sulfate in the soil (it is also toxic to some plants), reduced to sulfide in the atmosphere, or oxidized to sulfate in the atmosphere as sulfuric acid, a principal component of acid rain
