Fe has an oxidation number of
As Br has an oxidation number of -1 in bromide, only two salts of Fe with Br are possible:
a)3 b)2 c)1 d)4 Fe is the transitional metal K3[Fe(CN)6] , we know that Potassium, K, has an oxidation number of +1 The oxidation number of CN= -1, so 6*CN has an oxidation number of -6 so therefore Fe - 6 = -3 Fe = -3 + 6 = +3 The oxidation number of Fe is +3. so A
+2 O.S. of Fe
It contains only two elements. Fe shows +3 number. Chlorine shows -1 as the oxidation number.
oxidation state of Fe in FeCl3 is +3. Cl has oxidation number -1 in this case Fe share 3 electrons with Cl so its oxidation state is +3.
+2 for Fe, -2 for O

oxidation state of Fe in FeCl3 is +3. Cl has oxidation number -1 in this case Fe share 3 electrons with Cl so its oxidation state is +3.
+2 for Fe, -2 for O
+3 for Fe -2 for S
Fe3O4 can be considered to be 1:1 mixture of FeO and Fe2O3. Oxidation number in FeO: +2 for Fe and -2 of O Oxidation number in Fe2O3: +3 for Fe and -2 of O
+3 for each Fe, -2 for each S
+3 for Fe -2 for S
O = 2-, Fe = 3+.
+3 for Fe and -2 for O.
+2 for Fe2+ ion
