Ionic and Net Ionic Equation (Chapter 4)



Reactions that occur in solution between ions and are called ionic reactions. Solution of soluble strong electrolytes often yield an insoluble product which appear as a precipitate. Equation for these reactions can be writen in three different ways. In molecular equations, complete formulas for all reactants and products are used. In an ionic equation, soluble strong electrolytes are written in dissociated (ionized) from: “molecular” formulas are used for solids and weak electrolytes. A net ionic equation is obtained by eleminating spectator ions from the ionic equation., and such an equation allows us to identify other combination of reactants that give the same net reaction. An ionic equation is balanced only if both atoms and net charge are balance.
