Question
Identify from the reaction the reactants that undergo oxidation and reduction.
Fe + S → FeS
Advertisements
Solution 1
Fe + S → FeS
In a reaction, Fe is changing to FeS. That means, iron loses electrons to form FeS. Loss of electron from a substance is called oxidation, so iron undergoes oxidation.
Solution 2
Iron (Fe) undergoes oxidation and Sulphur (S) undergoes reduction.
