Net Ionic Equations and Solubility

The video tutorial explains how to write the net ionic equation for the reaction between lead(II) nitrate and sodium carbonate. It begins with balancing the molecular equation, then determining the solubility states of the reactants and products. The tutorial proceeds to split strong electrolytes into ions to form the complete ionic equation. Finally, it identifies and removes spectator ions to derive the net ionic equation, emphasizing the formation of lead(II) carbonate as a precipitate.
