Chemical Reactions and Ionic Equations

This video tutorial explains how to balance the net ionic equation for copper(II) sulfate and sodium phosphate. It begins with balancing the molecular equation, then determining the solubility and states of the compounds involved. The tutorial proceeds to split the compounds into ions to form the complete ionic equation, and finally, it identifies and removes spectator ions to derive the net ionic equation. The video concludes with a summary of the balanced net ionic equation, ensuring both atom and charge balance.
