Chapter 23, Problem 23.25P

Interpretation Introduction

Interpretation:

In the given oxides ${\text{Mn}}_{\text{2}}{\text{O}}_{\text{3 }}$ or ${\text{Mn}}_{\text{2}}{\text{O}}_{\text{7 }}$ which one is more basic in water has to be find out.

Concept Introduction:

Oxides of metals and non-metals may be,

Acidic        -    exhibits acidic character

Basic        -    exhibits basic character

Oxides of metals with higher oxidation number of the main group elements are highly acidic whereas those with lesser oxidation number exhibit measurable basic properties.

Reaction of basic metallic oxides with water results in metal hydroxides.
