Net Ionic Equations and Reactions

This video tutorial explains how to write a balanced net ionic equation for the reaction between zinc metal and iron(II) sulfate. It begins by ensuring the molecular equation is balanced and identifying the states of each substance. The tutorial then describes the single replacement reaction, where zinc displaces iron. It proceeds to form the complete ionic equation by splitting strong electrolytes into ions and identifies spectator ions to derive the net ionic equation. The video concludes by verifying that both charge and atoms are balanced in the final equation.
