In some cases, the average oxidation state of an element is a fraction, such as 8/3 for iron in magnetite (Fe 3 O 4). S + 4(-2) = -2. If the molecule is neutral, all of the oxidation numbers have to add up to zero. The sulfate ion is SO42- therefore S has an oxidation number of +6 (oxygen is -2 and Fe is +2) 0 0 0. Fe=+2.

Fe +2 S +6 O -2 4 + K +1 Mn +7 O -2 4 + H +1 2 S +6 O -2 4 → Fe +3 2 ( S +6 O -2 4 ) 3 + K +1 2 S +6 O -2 4 + Mn +2 S +6 O -2 4 + H +1 2 O -2 FeSO4 + KMnO4 + H2SO4 react to provide the Iron(II) sulphate ions. Source(s): Periodic table. Answer Save. (Fe has lost 2 electrons to form the bond with SO4(2-) ions) yeah so the mass of Fe has changed. 0 0 211; Luke. I know oxygen is -2, so 4(-2). Lv 5. 1. Sulphur has +6. B. Magnesium has 1+ oxidation number and chlorine has a 12 oxidation number. Group 2 metals = +2 4. Oxygen has +2. 0 0. Fe 3 O 4 contains Fe atoms of both +2 and +3 oxidation number. The highest known oxidation state is +8 in the tetroxides of ruthenium, xenon, osmium, iridium, hassium, and some complexes involving plutonium; the lowest known oxidation state is −4 for some elements in the carbon group. Answered What is the oxidation number of Fe in FeSO4… It has lost electrons, so it is oxidised. Fe is 2+ You can set it up like this. Oxidation rules: 1. K2Cr2O7 FeSO4 H2SO4 are reacts to give multiple products. 8 years ago. S=+6. It is a stoichiometric mixture of Ferrous (FeO) and Ferric (Fe 2 O 3) oxides combined as FeO.Fe 2 O 3.Therefore, the oxidation number found in such cases is average oxidation number. What is my next step? FeSO4 charge is neutral. Anonymous. Fe goes from oxidation number 0 to +2. Fe2 = +6; Fe = +3. 0 0. marypquinn. Fe(CO5) let oxidation state of fe be . Is the Fe2 being reduced and the Fe being oxidized? 8 years ago. Answer for question: Your name: Answers. xH 2 O. 6 years ago. for that reason, the Fe you're utilising is Fe(II) and not Fe(III). SO4(2-) The oxidation numbers of all the atoms have to add up to -2. S= 3. Fe + H 2 SO 4 → FeSO 4 + H 2 [ Check the balance ] Iron react with sulfuric acid to produce iron(II) sulfate and hydrogen. The oxidation number of each atom can be calculated by subtracting the sum of lone pairs and electrons it gains from bonds from the number of valence electrons. Charge of sulfur in FeSO4 is +6. Answer Save. 2. Thermodynamic properties of substances The solubility of the substances Periodic table of elements. vaishnavi102002 vaishnavi102002 17.11.2018 Chemistry Secondary School +5 pts. S = -2 + 8 . Oxidation number (also called oxidation state) is a measure of the degree of oxidation of an atom in a substance (see: Rules for assigning oxidation numbers). Cu goes from ON. convert 2(NH4)3PO4+3HgSO4=3(NH4)2SO4+Hg3(PO4)2 into complete ionic equation,then net ionic equation . Picture of reaction: Сoding to search: Fe + H2SO4 = FeSO4 + H2.
