Chapter 22, Problem 46E

Interpretation Introduction

(a)

Interpretation:

To give the reaction with elemental sulfur, chlorine gas, metallic sodium, water, and air to produce aqueous solutions of ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{3}}$.

Concept introduction:

Sulfur reacts with oxygen to produced sulfur dioxide. Sulfur dioxide reacts with water to form ${\text{H}}_{\text{2}}{\text{SO}}_{\text{3}}$. The product formed ${\text{H}}_{\text{2}}{\text{SO}}_{\text{3}}$ reacts with metallic sodium and produced $\text{NaOH}$ and ${\text{H}}_{\text{2}}$. At last $\text{NaOH}$ react with ${\text{H}}_{\text{2}}{\text{SO}}_{\text{3}}$ and produced ${\text{Na}}_2{\text{SO}}_{\text{3}}$.

Interpretation Introduction

(b)

Interpretation:

To give the reaction with elemental sulfur, chlorine gas, metallic sodium, water, and air to produce aqueous solutions of ${\text{Na}}_{\text{2}}{\text{SO}}_4$.

Concept introduction:

Sulfur dioxide reacts with oxygen to produced sulfur trioxide. Sulfur trioxide reacts with water to form ${\text{H}}_{\text{2}}{\text{SO}}_4$. On reaction between ${\text{H}}_{\text{2}}{\text{SO}}_{\text{3}}$ and metallic sodium $\text{NaOH}$ and ${\text{H}}_{\text{2}}$ are formed. The product formed $\text{NaOH}$ react with ${\text{H}}_{\text{2}}{\text{SO}}_4$ and produced ${\text{Na}}_2{\text{SO}}_4$.

Interpretation Introduction

(c)

Interpretation:

To give the reaction with elemental sulfur, chlorine gas, metallic sodium, water, and air to produce aqueous solutions of ${\text{Na}}_{\text{2}}{\text{S}}_2{\text{O}}_3$.

Concept introduction:

Sulfur reacts with oxygen to produced sulfur dioxide. Sulfur dioxide reacts with water to form ${\text{H}}_{\text{2}}{\text{SO}}_{\text{3}}$. Again elemental sulfur reacts with ${\text{H}}_{\text{2}}{\text{SO}}_{\text{3}}$ and produced ${\text{H}}_{\text{2}}{\text{S}}_{\text{2}}{\text{O}}_{\text{3}}$.
