Net Ionic Equation Includes only those species undergoing a change in the reaction. That is, spectator ions  are not included. Thus, for the reaction above the net ion equation would be H + (aq)  + OH - (aq)    H 2 O (aq) As you might imagine, it is possible to mix substances and have no net ionic equation.  Consider the following molecular equation CaCl 2 (aq)  + 2 HNO 3 (aq)    Ca(NO 3 ) 2 (aq)  + 2 HCl (aq) The complete ionic equation is Ca 2+ (aq)  + 2 Cl - (aq)  + 2 H + (aq)  + 2 NO 3 - (aq)    Ca 2+ (aq)  + 2 NO 3 - (aq)  + 2 H + (aq)  + 2 Cl - (aq) Removing all the spectator ions from this equation leaves nothing! All the ions are  spectator ions, so there is no net ionic reaction.

Unformatted text preview: Processes that lead to a Net Ionic Equation We will now consider the following four processes that will lead to an actual net ionic equation: Formation of an insoluble solid (Precipitation Reaction) Formation of a gas that escapes from solution Formation of either a weak electrolyte or non-electrolyte An oxidation/reduction reaction The first three processes are generally reactions where a cation meets up with an anion and forms a bond that has enough covalent character that they can no longer be separated into individual cations and anions any more....
