Balancing Net Ionic Equations

The video tutorial explains how to balance the net ionic equation for lead(II) nitrate and ammonium phosphate. It begins with balancing the molecular equation, followed by assigning states to each substance based on solubility rules. The tutorial then demonstrates how to split strong electrolytes into ions to form the complete ionic equation. Finally, it identifies and removes spectator ions to derive the net ionic equation, ensuring charge and atom balance.
