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.
