Answer:
The oxygen element in H2O2 is the specie that is reduced in H2O and oxidized into O2.
Explanation:
5 H2O2(aq) + 2 MnO4-(aq) + 6 H+(aq) → 2 Mn2+(aq) + 8 H2O(l) + 5 O2(g)
Oxidation is defined as the outright loss of electrons. Oxidation leads to an increase in an element's oxidation number.
If this reaction is broken down into reduction and oxidation halves
It is observed that, of the reactants above,
H202 becomes H2O and O2
MnO4- + H+ becomes Mn2+ and H2O
Oxidation number of Mn changes from +7 In MnO4- to +2 In Mn2+ (evidently reduction)
The Oxygen in MnO4- doesn't change oxidation numbers as its oxidation number stays at -2
Oxidation number of Oxygen changes from -1 in H2O2 to -2 In H2O and 0 in O2
The Hyrogen in H2O2 doesn't change oxidation numbers, itsoxidation number stays at +1 in H2O2 and H2O.
This indicates that H2O2 undergoes oxidation and reduction; more specifically, the oxygen element in H2O2 is the specie that is reduced in H2O and oxidized into O2.
Hope this Helps
The correct answer is option C, that is, it is reduced.
In reduction and oxidation reactions, reduction refers to the loss of an oxygen atom from a molecule or the gaining of one or more electrons. A reduction reaction is observed from the perspective of the molecule being reduced, as when one molecule gets reduced, another one gets oxidized. The complete reaction is called a redox reaction.
In the given case, iron gains electrons mean that it is reduced.
