Chapter 19, Problem 19.65QP

(a)

Interpretation Introduction

Interpretation:

In the development of lightweight batteries, the reducing agent that reacts spontaneously with oxygen should be suggested and its drawbacks should be given.

Concept introduction:

Standard reduction potential:

The reducing tendencies of the chemical species are measured at $\text{1M}$ concentration and 1atm pressures for all gases are called standard reduction potential.

In electrochemistry standard reduction potential for Hydrogen is assumed to zero then respect with this, the standard reduction potential for others species are measured and these measured standard reduction potential are arranged in the increasing ordered, this is known as standard reduction potential table.
