Chapter 16, Problem 115QP

Interpretation Introduction

Interpretation:

The given group of oxides are to be arranged in the increasing order of their basicity.

Concept introduction:

Elements combine with oxygen atom(s) to form oxides. They, then, react with water to either 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 a high 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 showacidic as well as basic natures, according to the reaction conditions. These are called amphoteric oxides.
