Net Ionic Equations and Spectator Ions

This video tutorial explains how to write a balanced net ionic equation for the reaction between hydrochloric acid (HCl) and zinc carbonate (ZnCO3). It begins with balancing the molecular equation, then determining the states of each substance. The tutorial proceeds to split strong electrolytes into ions to form the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. The video concludes by ensuring the charge is balanced and the atoms are accounted for in the final equation.
