Net Ionic Equations and Electrolytes

The video tutorial explains how to write the balanced net ionic equation for the reaction between potassium carbonate and sulfuric acid. It covers the steps to balance the molecular equation, assign states to each substance, and split strong electrolytes into ions. The tutorial then demonstrates how to form the complete ionic equation and identify spectator ions to derive the net ionic equation. Finally, it emphasizes the importance of conserving charge and mass in the reaction.
