Chapter 17, Problem 66E

Interpretation Introduction

Interpretation:

The information regarding ${\text{TlI}}_3$ is given. The formulation of given compound ${\text{TlI}}_3$ as thallium $\left(\text{I}\right)$ triiodide or as thallium $\left(\text{III}\right)$ iodide is to be stated.

Concept introduction:

The species with higher reduction potential undergoes reduction while the species with lower reduction potential undergoes. The change in Gibbs free energy is the useful amount of work that can be done and negative value of $\Delta G°$ shows that the reaction is spontaneous in nature.

To determine: The formulation of given compound ${\text{TlI}}_3$ as thallium $\left(\text{I}\right)$ triiodide or as thallium $\left(\text{III}\right)$ iodide.
