Chapter 20, Problem 66E

Interpretation Introduction

Interpretation: The reason for the fact that $\text{HF}$ is a weak acid, whereas $\text{HCl},\text{HBr}$ and $\text{HI}$ is all strong acids is to be stated.

Concept introduction: Strong acids give away ${\text{H}}^{+}$ ion easily, whereas weak acids do not. The acidic strength of hydrogen halides $\left(\text{H}-\text{X}\right)$ depends on their bond strength. Higher the bond strength, lower will be the acidic strength.

To determine: An explanation for the fact that $\text{HF}$ is a weak acid, whereas $\text{HCl},\text{HBr}$ and $\text{HI}$ is all strong acids.
