Net Ionic Equations and Electrolytes

The video tutorial explains how to write a balanced net ionic equation for the reaction between copper(II) 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. Spectator ions are identified and removed to derive the net ionic equation. Finally, the tutorial ensures that both atoms and charges are balanced, concluding with a balanced net ionic equation.
