Question
Chapter 14, Problem 40E
Interpretation Introduction
Interpretation:
The given statement “a health-related website recommended taking small amounts of iodine as antioxidant to prevent aging” is to be explained.
Concept Introduction:
Oxidation is the addition of an electronegative element or the removal of an electropositive element in a
Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction.
A chemical reaction in which oxidation process and reduction process take place simultaneously is called a redox reaction.
An oxidizing agent is a substance that has the capacity to oxidize the other substances and get reduced in a chemical reaction.
A reducing agent is a substance that has the capacity to reduce the other substances and get oxidized in a chemical reaction.
An antioxidant is a reducing agent. The reducing agent loses electrons easily in the chemical reaction. It reduces the other substances and gets oxidized in the
Iodine is an oxidizing agent. So, iodine will not work as an antioxidant.
