Chapter 19, Problem 109AP

Interpretation Introduction

Interpretation:

The effect on thestrength of fluorine as an oxidizing agent with the increasing concentration of ${\text{H}}^{\text{+}}$ is to be described.

Concept introduction:

Oxidizing agents have greater tendency to accept electrons or easily reduced, therefore they are strong oxidizing agents.

AlthoughF has lower electron affinity than Cl, low dissociation energy and a high hydration energy of its ion makes it the strongest oxidizing agent.

The Nernst equation is as follows:

$E=E^{\circ }-\frac{\text{R}T}{n\text{F}}\ln Q$

$E=E^{\circ }-\frac{0.0592}{n}\mathrm{l}\text{og}Q$

Here, R is the gas constant, $T$ is the temperature, $E$ is the emf of the cell, $E^{\circ }$ is the standard cell potential, F is the Faraday’s constant, and $Q$ is reaction constant.
