Net Ionic Equations and Reactions

The video tutorial explains how to write a balanced net ionic equation for the reaction between nitric acid (HNO3) and ammonium hydroxide (NH4OH). It begins with balancing the molecular equation, assigning states to each substance, and then breaking down strong electrolytes into ions for the complete ionic equation. The tutorial proceeds to derive the net ionic equation by removing spectator ions and concludes with a discussion on charge conservation and atom balance.
