Chapter 16, Problem 16.173AP

(a)

Interpretation Introduction

Interpretation: The Lewis structure of ${\text{H}}_{\text{2}}{\text{S}}_{\text{2}}{\text{O}}_{\text{3}}$ is to be drawn. The comparison between the acidic strength of ${\text{H}}_{\text{2}}{\text{S}}_{\text{2}}{\text{O}}_{\text{3}}$ and ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ is to be done and explained.

Concept introduction: The Lewis structures are diagrams that give information about the bonding electron pairs and the lone pairs of electrons in a molecule. They are similar to electron dot structure.

To determine: The Lewis structure of ${\text{H}}_{\text{2}}{\text{S}}_{\text{2}}{\text{O}}_{\text{3}}$.

(b)

Interpretation Introduction

To determine: The stronger or weaker acid between ${\text{H}}_{\text{2}}{\text{S}}_{\text{2}}{\text{O}}_{\text{3}}$ and ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ and the reason behind their acidic strength.
