Net Ionic Equations and Spectator Ions

This video tutorial guides viewers through the process of writing a balanced net ionic equation for the reaction between barium nitrate and sulfuric acid. It begins with balancing the molecular equation, followed by determining the states of each substance involved. The tutorial then explains how to split strong electrolytes into their ions to form the complete ionic equation. Finally, it demonstrates how to derive the net ionic equation by removing spectator ions, ensuring charge and atom balance, and concludes with a summary of the process.
