Net Ionic Equations and Balancing

The video tutorial explains how to write a balanced net ionic equation for the reaction between lead(II) acetate and sodium sulfate. It begins by introducing the concept of net ionic equations and the importance of balancing molecular equations. The tutorial then covers solubility rules, highlighting exceptions like lead(II) sulfate. It proceeds to demonstrate how to split strong electrolytes into ions for the complete ionic equation and identify spectator ions. Finally, it shows how to write the net ionic equation, ensuring both charge and atom balance.
