Question

What is the reducing agent in the following reaction? 12H+ + 2IO₃- + Fe⁽²⁺⁾ → 10Fe⁽³⁺⁾ + I2 + 6H₂O

1) Fe2+
2) H+
3) I2
4) IO₃-

Answer 1

In the given reaction, Fe²⁺ is the reducing agent because it is oxidized from Fe²⁺ to Fe³⁺.The correct answer is option 1.

Step-by-step explanation:

To determine the reducing agent in the reaction 12H+ + 2IO₃⁻ + Fe⁻²⁺ → 10Fe⁻³⁺ + I2 + 6H2O, we need to look at the changes in oxidation states of the reactants and products.

The iron (Fe) goes from a +2 oxidation state to a +3 oxidation state, which means it is losing electrons and is being oxidized.

According to the redox concept, the substance that is oxidized is the reducing agent because it provides electrons to the other substance. Therefore, Fe²⁺ is the reducing agent in this reaction.The correct answer is option 1.
