Chapter 21, Problem 21.163QP

Interpretation Introduction

Interpretation:

The standard $emf$ of given reaction has to be calculated.

Concept introduction:

Half reactions:

A half reaction can be defined as component of redox reaction that is either Oxidation or reduction reaction.  The change in oxidation states of individual substances present in redox reaction gives the half reaction.  Half reactions are common methods of balancing redox reactions.

${\text{E}}_{\text{cell}}\text{ = oxidation potential + reduction potential}$
