Chapter 4, Problem 18P

Interpretation Introduction

Interpretation:

The net-ionic equation for the given reaction should be determined.

Concept Introduction:

When two aqueous solutions are mixed together, this may or may not result in formation of an insoluble solid in the solution. This insoluble solid is called precipitate and this reaction is called precipitation reaction.

For example, a reaction in which A and C displace each other from their respective solutions. Since two displacement takes place, this reaction is also called double displacement reaction.

$\text{AB(aq)+CD(aq)}\stackrel{}{\to }\text{AD(s)+CB(aq)}$

AD(s) represents a precipitate.

Sometime a gaseous product is also formed, in that case we represent the equation with the phase mentioned as (g).

$\text{AB(aq)+CD(aq)}\stackrel{}{\to }\text{AD(g)}\uparrow \text{+CB(aq)}$.
