Net Ionic Equations and Reactions

This video tutorial explains how to write the net ionic equation for the reaction between nitric acid (HNO3) and sodium carbonate (Na2CO3). It begins with balancing the molecular equation, assigning states to each compound, and identifying which compounds dissociate in water. The tutorial then demonstrates how to write the complete ionic equation by splitting strong electrolytes into their ions. Finally, it shows how to derive the net ionic equation by removing spectator ions, resulting in a simplified equation that highlights the actual chemical change. The video concludes with a summary of the process.
