Net Ionic Equations and Spectator Ions

The video tutorial explains how to write a balanced net ionic equation for the reaction between copper(II) sulfate and ammonium phosphate. It begins with balancing the molecular equation and determining the states of substances 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. The tutorial concludes by ensuring the equation is balanced in terms of both atoms and charges.
