Chapter 18, Problem 18.18QP

Interpretation Introduction

Interpretation: The given partial chemical equation is to be completed and balanced by the use of appropriate half-reactions in acidic conditions.

Concept introduction: The number of electrons involved in a redox reaction is always equal with the charge, which is transferred during the whole reaction. To balance “n” positive charges, “n” number of electrons is always involved.

The species which accepts electrons is known as, oxidizing agent while the species which donates electrons is known as, reducing agent. In other words the oxidizing agent is itself a reduced species while the reducing agent is itself an oxidized species.

To determine: The complete and balanced partial chemical equation by the use of appropriate half-reactions.
