Net Ionic Equations and Spectator Ions

The video tutorial explains how to write a balanced net ionic equation for the reaction between nitric acid (HNO3) and calcium hydroxide (Ca(OH)2). It begins with writing the balanced molecular equation and determining the states of the substances involved. The tutorial then covers splitting soluble substances into their respective ions and forming the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation, which represents the neutralization reaction. The process is explained step-by-step, ensuring clarity in understanding the formation of net ionic equations.
