Chapter 7, Problem 89AE

(a)

Interpretation Introduction

To determine: The smaller ion between ${\text{Co}}^{3+}$ and ${\text{Co}}^{4+}$ .

(b)

Interpretation Introduction

To determine: The order of ionic radii of ${\text{Li}}^{+},{\text{Co}}^{3+}$ and ${\text{Co}}^{4+}$ and arrange it from smallest to largest.

(c)

Interpretation Introduction

To determine: The lithium cobalt oxide cathode will expand or contract when the lithium ions are inserted.

(d)

Interpretation Introduction

To determine: If the introduction of sodium ions rather than lithium ion in batteries, sodium cobalt oxide will work in the same manner as the electrode material.

(e)

Interpretation Introduction

To determine: The alternative metal ion that can work as the redox-active partner ion in sodium version of electrode.
