Chapter 16, Problem 114QP

Interpretation Introduction

Interpretation:

The reason that metal oxideshow an acidic nature in a high oxidation state, while show a basic nature in a low oxidation state, is to be explained.

Concept Introduction:

Elements combine with oxygen atom(s) to form oxides. They, then, react with water toeither produce an acid or a base.

In their lowest oxidation number, all alkali and alkaline earth metal oxides are basic in nature.

Some metal oxides, in ahigh oxidation state, show acidic behavior.

All nonmetal oxides are acidic in nature in their highest oxidation state. They are considerably neutral in their low oxidation state. In any case, nonmetal oxides do not show basic nature.

Metallic oxides show acidic as well as basic natures, according to the reaction conditions. These are called amphoteric oxides.
