Net Ionic Equations and Reactions

The video tutorial explains how to write a balanced net ionic equation for the reaction between magnesium and zinc sulfate. It begins by balancing the molecular equation and determining the states of each substance. The tutorial then demonstrates how to split strong electrolytes into ions to form the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. Finally, the video verifies that charge and atom balance are maintained in the net ionic equation.
