Net Ionic Equations and Solubility

The video tutorial explains how to write the balanced net ionic equation for the reaction between sodium bicarbonate (NaHCO3) and acetic acid (HC2H3O2). It begins by introducing the reactants and confirming that the molecular equation is already balanced. The video then discusses the solubility and states of the reactants, identifying acetic acid as a weak acid. The tutorial proceeds to split strong electrolytes into ions to form the complete ionic equation, and then removes spectator ions to derive the net ionic equation. The final section emphasizes charge conservation and atom balance in the net ionic equation.
