Net Ionic Equations and Spectator Ions

The video tutorial explains how to write the net ionic equation for the reaction between calcium acetate and sodium carbonate. It begins with balancing the molecular equation, identifying the states of each compound, and discussing solubility. The tutorial then demonstrates how to write the complete ionic equation, identify and remove spectator ions, and finalize the net ionic equation. The video concludes with a verification of charge and atom balance.

What is the purpose of writing a net ionic equation?
