Chapter 5, Problem 25E

Interpretation Introduction

(a)

Interpretation:

The reagents to obtain ${\text{SrSO}}_{\text{4}}(\text{s})$ should be chosen from provided salts. $\begin{array}{l}\text{NaOH (aq),}{\text{K}}_{\text{2}}{\text{SO}}_{\text{4}}\text{(aq),}{\text{Mg(NO}}_{\text{2}}{\text{)}}_{\text{2}}\text{(aq),}{\text{BaCl}}_{\text{2}}\text{(aq)},\text{NaCl(aq)},{\text{Sr(NO}}_{\text{2}}{\text{)}}_{\text{2}}{\text{(aq), AgNO}}_{\text{2}}\text{(aq) }\\ {\text{and BaSO}}_{\text{4}}(\text{s})\end{array}$.

Concept introduction:

In order to obtain a precipitate from a mixture, the two solutions which are going to mix should have precipitate’s anion and cation in an aqueous medium. If an insoluble solid is formed, then the expected precipitation does not occur.

Interpretation Introduction

(b)

Interpretation:

The reagents to obtain ${\text{MgOH}}_{\text{2}}(\text{s})$ should be chosen from provided salts. $\begin{array}{l}\text{NaOH (aq),}{\text{K}}_{\text{2}}{\text{SO}}_{\text{4}}\text{(aq),}{\text{Mg(NO}}_{\text{2}}{\text{)}}_{\text{2}}\text{(aq),}{\text{BaCl}}_{\text{2}}\text{(aq)},\text{NaCl(aq)},{\text{Sr(NO}}_{\text{2}}{\text{)}}_{\text{2}}{\text{(aq), AgNO}}_{\text{2}}\text{(aq) }\\ {\text{and BaSO}}_{\text{4}}(\text{s})\end{array}$.

Interpretation Introduction

(c)

Interpretation:

The reagents to obtain $\text{KCl }(\text{aq})$ should be chosen from provided salts. $\begin{array}{l}\text{NaOH (aq),}{\text{K}}_{\text{2}}{\text{SO}}_{\text{4}}\text{(aq),}{\text{Mg(NO}}_{\text{2}}{\text{)}}_{\text{2}}\text{(aq),}{\text{BaCl}}_{\text{2}}\text{(aq)},\text{NaCl(aq)},{\text{Sr(NO}}_{\text{2}}{\text{)}}_{\text{2}}{\text{(aq), AgNO}}_{\text{2}}\text{(aq) }\\ {\text{and BaSO}}_{\text{4}}(\text{s})\end{array}$.
