Net Ionic Equations and Solubility

The video tutorial explains how to write a balanced net ionic equation for the reaction between nickel(II) nitrate and potassium sulfide. It begins with balancing the molecular equation, followed by determining the solubility of the compounds involved. The tutorial then demonstrates how to write complete and net ionic equations, highlighting the role of spectator ions. Finally, it emphasizes the importance of conserving charge and balancing atoms in the reaction.
