Net Ionic Equations and Solubility

This video tutorial explains how to write a balanced net ionic equation for the reaction between barium nitrate and magnesium sulfate. It begins with balancing the molecular equation and identifying the solubility of the compounds involved. The video then breaks down the complete ionic equation, highlighting the ions present. Spectator ions are identified and removed to form the net ionic equation. The tutorial concludes by emphasizing the conservation of charge and the balance of atoms in the final equation.
