Question
In the reaction, 8Al + 3Fe3O4 → 4Al2O3 + 9Fethe number of electron transfered from reductant to oxidant is :341624
Solution
To determine the number of electrons transferred from the reductant to the oxidant in the given reaction, we need to examine the oxidation states of the elements involved.
In this reaction, aluminum (Al) is being oxidized from an oxidation state of 0 to +3 in aluminum oxide (Al2O3). Iron (Fe) is being reduced from an oxidation state of +3 in iron(III) oxide (Fe3O4) to an oxidation state of 0 in elemental iron (Fe).
Since each aluminum atom loses 3 electrons and there are 8 aluminum atoms involved, the total number of electrons lost by aluminum is 8 * 3 = 24 electrons.
Similarly, each iron(III) ion gains 3 electrons and there are 3 iron(III) ions involved, so the total number of electrons gained by iron is 3 * 3 = 9 electrons.
Therefore, the number of electrons transferred from the reductant (Al) to the oxidant (Fe) in this reaction is 24 electrons.
