Chapter 14, Problem 14.36P

Interpretation Introduction

Interpretation:

The increasing order of acidity aqueous solutions of ${\text{Ga}}_{\text{2}}{\text{O3, Al}}_{\text{2}}{\text{O}}_{\text{3}}{\text{, In}}_{\text{2}}{\text{O}}_{\text{3}}$ has to be given.

Concept Introduction:

Order of acidity in periodic table:

Across the left to right acidity is increases due to increasing electronegativity and up to down acidity is decreases due to increasing atomic size.
