Chapter 18, Problem 66E

Interpretation Introduction

Interpretation:

The formula of Thallium triiodide should be determined by using given reduction potentials.

Concept introduction:

Electromotive force:

The potential difference between two electros in the galvanic cell is known as electromotive force (EMF) and it is given by

${\text{E}}_{\text{cell}}\text{=}{\text{E}}_{\text{cathode}}{\text{-E}}_{\text{anode}}$

The loss of electron is oxidation and this is occurs in anode.

The gain of electron is reduction and this is occurs in cathode.

If the EMF is positive the cell reaction will take place spontaneously.

If the EMF is negative the cell reaction will not take place spontaneously.
