Net Ionic Equations and Ionic Charges

The video tutorial explains how to write the net ionic equation for the reaction between silver nitrate (AgNO3) and nickel(II) chloride (NiCl2). It begins by balancing the molecular equation, then discusses the solubility and states of the reactants and products. The tutorial proceeds to break down the reaction into ions to form the complete ionic equation, and then derives the net ionic equation by removing spectator ions. Finally, it emphasizes the conservation of charge and mass in the reaction.
