Chapter 4, Problem 4.72SP

Interpretation Introduction

(a)

Interpretation:

The given reaction ${\text{Hg(NO}}_{\text{3}}{\text{)}}_{\text{2}}\text{(aq)+2NaI(aq)}\underset{}{\to }{\text{2NaNO}}_{\text{3}}{\text{(aq)+HgI}}_{\text{2}}\text{(s)}$ is to be classified as oxidation-reduction, acid-base neutralization or precipitation reaction.

Concept introduction:

An oxidation reaction is defined as the reaction in which the loss of electrons takes place while the reduction reactions can be defined as the reactions where gain of electrons occurs. Redox reactions can be defined as the reaction in which reduction and oxidation take place simultaneously.

A neutralization reaction is a type of chemical reaction in which a base and an acid reacts in a quantitative manner and the product so formed are salt and water.

A precipitation reaction can be defined as the type of chemical reaction in which an insoluble salt is formed when two solutions consisting of soluble salts are combined together.

Interpretation Introduction

(b)

Interpretation:

The given reaction $\text{2HgO(s)}\stackrel{\text{heat}}{\to }{\text{2Hg(l)+O}}_{\text{2}}\text{(g)}$ is to be classified as oxidation-reduction, acid-base neutralization or precipitation reaction.
