Chapter 4, Problem 4.142AP

(a)

Interpretation Introduction

Interpretation: The questions corresponding to the given reaction between ${\text{BrO}}_{\text{3}}{}^{-}$ ions and ${\text{Br}}^{-}$ are to be answered.

Concept introduction: : The reactants and the products in a. given ionic equation must be balanced for the given number of ions or atoms of each element.

A compound is said to be oxidized when it loses electrons which increases its oxidation number. On the other hand reduction is the process of gaining electrons which decreases the oxidation number of the compound.

To determine: If ${\text{BrO}}_{\text{3}}{}^{-}\left(aq\right)$ is reduced or not.

(b)

Interpretation Introduction

To determine: The product of ${\text{BrO}}_{\text{3}}{}^{-}\left(aq\right)$ in the given reaction.

(c)

Interpretation Introduction

To determine: If ${\text{Br}}^{-}\left(aq\right)$ is oxidized or not.

(d)

Interpretation Introduction

To determine: The product of ${\text{Br}}^{-}\left(aq\right)$ in the oxidation reaction.
