Net Ionic Equations and Reactions

This video tutorial guides viewers through writing a balanced net ionic equation for the reaction between sulfuric acid (H2SO4) and barium bromide (BaBr2). It begins with balancing the molecular equation, assigning states to substances based on solubility rules, and then splitting strong electrolytes into ions for the complete ionic equation. The tutorial explains how to identify and remove spectator ions to form the net ionic equation, ensuring charge and atom balance. The video concludes with a verification of the final net ionic equation.
