Chapter 19, Problem 19.32SP

(a)

Interpretation Introduction

Interpretation:

From the given oxide pair ${\text{Al}}_{\text{2}}{\text{O}}_{\text{3}}\text{or}{\text{P}}_{\text{4}}{\text{O}}_{\text{10}}$, the one which is more acidic has to be identified.

Concept introduction:

Acidic oxide:

An acidic oxide is an oxide which when combined with water gives off an acid.  For the non-metal oxides, their acidity is usually thought of on terms of the acidic solution formed when they reacts with water.

(b)

Interpretation Introduction

Interpretation:

From the given oxide pair ${\text{B}}_{\text{2}}{\text{O}}_{\text{3}}\text{or}{\text{Ga}}_{\text{2}}{\text{O}}_{\text{3}}$, the one which is more acidic has to be identified.

Acidic oxide:

An acidic oxide is an oxide which when combined with water gives off an acid.  For the non-metal oxides, their acidity is usually thought of on terms of the acidic solution formed when they reacts with water.

(c)

Interpretation Introduction

Interpretation:

From the given oxide pair ${\text{SO}}_{\text{2}}\text{or}{\text{SnO}}_{\text{2}}$, the one which is more acidic has to be identified.

Concept introduction:

Acidic oxide:

An acidic oxide is an oxide which when combined with water gives off an acid.  For the non-metal oxides, their acidity is usually thought of on terms of the acidic solution formed when they reacts with water.

(d)

Interpretation Introduction

Interpretation:

From the given oxide pair ${\text{As}}_{\text{2}}{\text{O}}_{\text{3}}\text{or}{\text{N}}_{\text{2}}{\text{O}}_{\text{3}}$, the one which is more acidic has to be identified.
