Net Ionic Equations and Electrolytes

The video tutorial explains how to write a balanced net ionic equation for the reaction between calcium nitrate and sulfuric acid. It begins by balancing the molecular equation, then assigns states to each substance using solubility rules. The tutorial proceeds to split strong electrolytes into ions to form a complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. Finally, the tutorial ensures that both atoms and charges are balanced in the net ionic equation.
