Net Ionic Equations and Solubility

The video tutorial explains how to write a balanced net ionic equation for the reaction between copper(II) nitrate and sodium carbonate. It covers balancing the molecular equation, determining the states of substances using solubility rules, and using solubility charts to identify insoluble compounds. The tutorial then demonstrates how to split substances into ions, write the total ionic equation, and identify spectator ions. Finally, it shows how to finalize and balance the net ionic equation, ensuring that both atoms and charges are balanced.
