Chapter 15, Problem 15.135QP

Interpretation Introduction

Interpretation:

The hydration of $S{O}_2$ as a Lewis acid-bas reaction should be described.

Concept Introduction:

In Bronsted's theory acid donates proton, while base accepts proton from acid resulting in the formation of water.

According to Lewis theory, acid and base can be defined as follows.

Lewis Acid:

Lewis acid is a substance that can accept a pair of electrons

Example: $\text{BF}{\text{3}}_{}$

Lewis Base:

Lewis base is a substance that can donate a pair of electrons.

Example: ${\text{NH}}_{\text{3}}$
