Net Ionic Equations and Charges

This video tutorial explains how to write a balanced net ionic equation for the reaction between iron(II) chloride (FeCl2) and zinc (Zn). It begins with balancing the molecular equation, followed by assigning states to each substance using solubility rules. 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. The video concludes by ensuring that both charge and atoms are balanced in the final equation.
