Net Ionic Equations and Spectator Ions

The video tutorial explains how to write a balanced net ionic equation for the reaction between magnesium nitrate and ammonium carbonate. It begins with balancing the molecular equation, followed by determining the states of each substance using solubility rules. The tutorial then demonstrates how to split strong electrolytes into ions to form the complete ionic equation. Finally, it shows how to identify and remove spectator ions to derive the net ionic equation, ensuring both atoms and charges are balanced.
