Chapter 22, Problem 22.157SP

Interpretation Introduction

Interpretation:

The order of the acidic strength of $\text{HIO < HBrO}<\text{HClO}$ has to be justified.

Concept Introduction:

• According to Bronsted Lowry’s theory of acids and bases, an acid is a proton donor, and acidic strength increases with increase in the ability of a species to donate its proton(s).
• Now, $Acid\to conjugatebase+{\text{H}}^{\text{+}}$.If the conjugate base is stable, the acid loses ${\text{H}}^{\text{+}}$easily.

Therefore, in order to know the acidic strength of an acid, the stability of its conjugate base has to be determined 1^st.

Given:

The order of acidic strength: $\text{HIO < HBrO}<\text{HClO}$
