Chapter 3, Problem 109QP

Interpretation Introduction

Interpretation:

The chemical formulae of all substances involved in the process are to be identified.

Concept Introduction:

Metals are present in the solid state while ionic compounds are present in the aqueous state because ionic compounds dissolve in water and dissociate into their respective ions. For example, $\text{Cu}{\left({\text{NO}}_3\right)}_2\left(aq\right)$ and ${\text{AgNO}}_3\left(aq\right)$ ionize into their respective ions by the following reactions:

$\begin{array}{l}\text{Cu}{\left({\text{NO}}_3\right)}_2\left(aq\right)\to {\text{Cu}}^{2+}\left(aq\right)+2{\text{NO}}_3^{-}\left(aq\right)\\ \left(\begin{array}{l}\text{Ionic }\\ \text{compound}\end{array}\right)\left(\text{cation}\right)\left(\text{anion}\right)\end{array}$

$\begin{array}{l}{\text{AgNO}}_3\left(aq\right)\to {\text{Ag}}^{+}\left(aq\right)+{\text{NO}}_3^{-}\left(aq\right)\\ \left(\begin{array}{l}\text{Ionic }\\ \text{compound}\end{array}\right)\left(\text{cation}\right)\left(\text{anion}\right)\end{array}$
