Net Ionic Equations and Solubility

This video tutorial explains how to write the net ionic equation for the reaction between sodium phosphate (Na3PO4) and barium chloride (BaCl2). It covers balancing the molecular equation, determining the solubility and states of the compounds, forming the complete ionic equation, and identifying spectator ions to derive the net ionic equation. The tutorial also emphasizes the importance of checking for errors in the final equation.
