Chapter 8, Problem 32A

Interpretation Introduction

Interpretation :

Which reaction is also called a double displacement reaction must be explained.

Concept Introduction :

In a double displacement reaction the ions are exchanged from two salts.

Answer to Problem 32A

A precipitation is also called a double displacement reaction.

Explanation of Solution

  ${\text{AgNO}}_{\text{3}}\text{(aq)+NaCl(aq)}\to {\text{AgCl(s)+NaNO}}_{\text{3}}\text{(aq)}\text{.}$

A double displacement reaction is shown in which Na displaces Ag.

A precipitate of AgCl is formed. Thus it is also a precipitation reaction.

Conclusion

Thus, a precipitation reaction is also a double displacement reaction.
