Net Ionic Equations and Concepts

This video tutorial explains how to write a balanced net ionic equation for the reaction between sodium bicarbonate (NaHCO3) and nitric acid (HNO3). It begins with balancing the molecular equation, then assigns states to each substance. The tutorial proceeds to split strong electrolytes into ions for the complete ionic equation, identifies and removes spectator ions, and finalizes the net ionic equation. The video emphasizes the importance of ensuring the net charge is zero and the atoms are balanced.
