10. Net Ionic Equations A complete ionic equation is an equation that shows dissolved ionic compounds as dissociated free ions. 11.3

11. Net Ionic Equations Spectator Ion: An ion that appears on both sides of an equation and is not directly involved in the reaction Net ionic equation: Equation for a reaction in solution that shows only those particles that are directly involved in the chemical change. 11.3

12. Predicting the Formation of a Precipitate 11.3 Precipitate: solid that forms and settles out in a chemical reaction You can predict the formation of a precipitate by using the general rules for solubility of ionic compounds.
