How is the oxidation of #"ferrous ion"# to #"ferric ion"# by
2017年5月16日 · Explanation: Oxidation reaction (i): F e2+ → F e3+ +e−. Reduction reaction (ii): M nO− 4 + 8H + +5e− → M n2+ +4H 2O(l) For both (i) and (ii), charge is balanced and mass is balanced, as indeed they must be if we purport to represent chemical reality. The final redox reaction adds 5 × (i) +(ii) so that electrons, conceptual particles ...

How does iron react with oxygen? - Socratic
2015年8月28日 · 1 Answer. Iron can react with oxygen to form two of its oxides, iron (II, III) oxide and iron (III) oxide. Upon reacting with oxygen, iron will be oxidized to either the +3 oxidation state in iron (III) oxide, or to a combination of the +2 and +3 oxidation states in iron (II, III) oxide. The balanced chemical equations for these reactions look ...
What is the formula for iron (II) oxide? - Socratic
2018年7月6日 · The formula for the iron (II) ion is [Math Processing Error] and the formula for the oxide ion is [Math Processing Error]. An ionic compound is neutral, so the positive and negative charges are equal. In the case of iron (II) oxide, one [Math Processing Error] ion combined with one [Math Processing Error] ion creates a neutral compound.
