Net Ionic Equations and Spectator Ions

This video tutorial explains how to write the balanced net ionic equation for the reaction between silver fluoride (AgF) and sodium iodide (NaI). It begins with balancing the molecular equation, followed by determining the states of each substance using a solubility table. The video then demonstrates how to split strong electrolytes into their ions to form the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. The tutorial concludes with a review of the balanced net ionic equation, ensuring that both charge and atoms are balanced.
