The more-electronegative element in a binary compound is assigned the number equal to the charge it would have if it were an ion. The oxidation number of a monatomic ion equals the charge on the ion. KMnO4 + HCI MnCl2 + Cl2 + H2O+KCI Oxidized: Reduced: 8. The oxidation number of any uncombined element is 0. HNO3 + HINO +12 + H2O Oxidized: Reduced 7. C + H2SO4 → CO, + SO2 + H2O Oxidized: Reduced: 6. 2 As(s) + 3 Cl2 (g) → 2 AsCl Oxidized: Reduced: 4. Part B: Identify the species being oxidized and reduced in each of the following reactions. Part A: In the following questions, give the oxidation number of the indicated atoms/ion: 1. Minimum oxidation number is it's classical group number minus 8. Maximum oxidation number is equal to its classical group number. The sum of the oxidation numbers in a polyatomic ion equals the charge of the ion. The sum of the oxidation numbers of all atoms in a neutral compound is 0. In compounds, Group 1 is +1, Group 2 is +2, and Aluminum is +3. Hydrogen is +1, unless combined with a metal, and then it is -1. Oxygen has an oxidation number of -2 (there are cases where it is not, for your examples it will be -2) 6. The oxidation number of fluorine in a compound is always -1. The more electronegative element in a binary compound is assigned the number equal to the charge it would have if it were an ion. The oxidation number of a monatomic ion equals that charge on the ion. The oxidation number of any pure element is 0.
