Chemical Reactions and Ionic Equations

This video tutorial explains how to write the net ionic equation for the reaction between sodium phosphate (Na3PO4) and silver nitrate (AgNO3). It begins with balancing the molecular equation, then discusses the solubility of the compounds involved, identifying silver phosphate as a precipitate. The tutorial proceeds to break down the compounds into their respective ions to form the complete ionic equation. Spectator ions are identified and removed to derive the net ionic equation. The video concludes with a neat presentation of the final net ionic equation.
