Chapter 19.5, Problem 19.3PSP

Interpretation Introduction

Interpretation:

Oxidizing and reducing agents in the second step of extraction of iodine from Chilean ores has to be identified.

Concept Introduction:

Oxidizing agent is the one that gets reduced during a chemical reaction and reducing agent is the one that gets oxidized in a chemical reaction.  In terms of electron transfer oxidizing agent is the one that donates electrons and reducing agent is the one that accepts electrons.  In terms of oxidation number, the oxidizing agent is the one where the element gains electrons results in decrease of oxidation number and reducing agent is the one where the element loses electrons results in increase of oxidation number.
