Net Ionic Equations and Electrolytes

This video tutorial guides viewers through the process of writing a balanced net ionic equation for the reaction between sodium hydroxide and iron(III) chloride. It begins with balancing the molecular equation, followed by determining the states of each substance involved. The tutorial then explains how to write the complete ionic equation by splitting strong electrolytes into their ions. Finally, it demonstrates how to derive the net ionic equation by removing spectator ions, ensuring that both charge and atom balance are maintained.
