On further heating, anhydrous ferrous sulphate decomposes to form ferric oxide (F e 2 O 3 ), sulphur dioxide (S O 2 ) and sulphur trioxide (S O 3 ). True but understand why you switch thats important.....Say we want the oxidation of sulfur S in FeSO4 we first find O= 4(-2)= -8 Then Fe is +2 So.....-8+2= -6 but Sulfur does not have 6 electrons it needs six due to the inductive effect so we indicate S needs +6 rather then -6 funky I know but when you draw the lewis structures and treat all as Ionic bonds it makes sense. © 2008-2010 . C. college. S the oxidation number of sulfur is +6. Here is a reaction: 2Al+3H2SO4--->Al2(SO4)+3H2 determine the oxidation numbers of each element in both the rectants and the products of this oxidation reduction reaction of aluminum and sulfuric acid? 8:6 ration is simplified as 4:3 . Sulfur must then have an oxidation number of +6, since +6 + (-8) = -2, the total charge on the ion. The oxidation number of sulphur in sulphuric acid h2so4 is?
