Chapter 5, Problem 26E

Interpretation Introduction

(a)

Interpretation:

The reagents to obtain ${\text{BaSO}}_{\text{4}}(\text{s})$ should be chosen from provided salts. $\begin{array}{l}\text{NaOH (aq),}{\text{K}}_{\text{2}}{\text{SO}}_{\text{4}}\text{(aq),}{\text{Mg(NO}}_3{\text{)}}_{\text{2}}\text{(aq),}{\text{BaCl}}_{\text{2}}\text{(aq)},\text{NaCl(aq)},{\text{Sr(NO}}_{\text{2}}{\text{)}}_{\text{2}}{\text{(aq), AgNO}}_{\text{2}}\text{(aq) }\\ {\text{and BaSO}}_{\text{4}}(\text{s})\end{array}$.

Concept introduction:

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

Interpretation Introduction

(b)

Interpretation:

The reagents to obtain $\text{AgCl }(\text{s})$ should be chosen from provided following salts. $\begin{array}{l}\text{NaOH (aq),}{\text{K}}_{\text{2}}{\text{SO}}_{\text{4}}\text{(aq),}{\text{Mg(NO}}_3{\text{)}}_{\text{2}}\text{(aq),}{\text{BaCl}}_{\text{2}}\text{(aq)},\text{NaCl(aq)},{\text{Sr(NO}}_{\text{2}}{\text{)}}_{\text{2}}{\text{(aq), AgNO}}_{\text{2}}\text{(aq) }\\ {\text{and BaSO}}_{\text{4}}(\text{s})\end{array}$.

Interpretation Introduction

(c)

Interpretation:

The reagents to obtain ${\text{KNO}}_{\text{3}}(\text{aq})$ should be chosen from provided following salts. $\begin{array}{l}\text{NaOH (aq),}{\text{K}}_{\text{2}}{\text{SO}}_{\text{4}}\text{(aq),}{\text{Mg(NO}}_3{\text{)}}_{\text{2}}\text{(aq),}{\text{BaCl}}_{\text{2}}\text{(aq)},\text{NaCl(aq)},{\text{Sr(NO}}_{\text{2}}{\text{)}}_{\text{2}}{\text{(aq), AgNO}}_{\text{2}}\text{(aq) }\\ {\text{and BaSO}}_{\text{4}}(\text{s})\end{array}$.
