Chapter 4.6, Problem 4.8Q

Interpretation Introduction

Interpretation:

The net ionic equation for the reaction of ${\text{Na}}_{\text{2}}{\text{CO}}_{\text{3}}$ solution mixed with ${\text{CaCl}}_{\text{2}}$ has to be written.  The precipitate formed in the reaction has to be identified.

Concept Introduction:

Net ionic Equation:

The net ionic equation shows only those chemical species that actually undergo chemical change.  The ions that do not change during the chemical reaction are called spectator ions.  These spectator ions are not shown in net ionic equation.
