What is the oxidation number of sulphur in ferric sulphate and ferrous sulphate |
| Answer» SULPHATE : IRON (III) sulphate VALENCY of iron is 3. Chemical formula: Fe₂ (SO₄)₃ IONS: Fe³⁺ and SO₄²⁻oxidation number of Fe is +3 oxidation number of SO₄ is -2 Oxidation number of oxygen (in general) is - 2 hence, - 2 = S + 4 * -2 => S = 6 oxidation number of Sulphur in Ferric Sulphate 6===================Ferrous sulphate or Iron (II) suplhate : chemical formula: Fe SO₄ Here Iron has valency - oxidation number 2. as the ions are: Fe²⁺ SO₄²⁻Hence the oxidation number of Sulphur will be 6 like in the case of Ferric sulphate. It will be 6. | |
