Chapter 22, Problem 22.5P

(a)

Interpretation Introduction

Interpretation:

The chemical equation and net ionic equations should be given if precipitation occurs if precipitation does not occur, and then no reaction has to be written.

  ${\text{CuCl}}_2{}_{\text{(aq)}}{\text{ +Na}}_{\text{2}}{\text{S}}_{\text{(aq)}}\to$

Concept Introduction:

Precipitation reaction:

• If precipitate is formed, when two solutions are mixed together is called precipitation reaction.

Balanced equation:

• The balanced equation is nothing but the all ionic compounds are represented as neutral compounds using the molecular formula.
• In the balanced equation, the number of atoms for each element and total charge are equal in the reaction for in both reactants and the products sides.

Ionic equation:

• In the ionic reactions, all the species present in reaction are written with respective charges is called ionic equation.

Net ionic equation:

• The equation contains only ionic spices that are actually participated in the formation of product is known as net ionic equation.
• The removal of spectator ions forms ionic equation to give net ionic equation.
