Net Ionic Equations and Solubility

The video tutorial explains how to write a balanced net ionic equation for the reaction between silver nitrate (AgNO3) and lithium chloride (LiCl). It begins with writing a balanced molecular equation and identifying the states of each substance using solubility rules. The tutorial then demonstrates how to split strong electrolytes into ions to form a complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. The video concludes with a balanced net ionic equation, ensuring the charges and atoms are balanced.
