NET IONIC EQUATIONS
Net ionic equations include only those reactants that
participate in a chemical change. Reactions of ions in
solutions are usually represented by net ionic equations
rather than formula equations because it shows what really
happened in the reactions.
1.
Start with a regular chemical equations showing ppt.
2.
Write ionic equation showing all dissolved dissociated ions
in solutions.
Notice: Which ions appear on both sides of the equation that have NOT
under-gone chemical change. These are called SPECTATOR IONS.
3.
To convert an ionic equation to a NET ionic equations the
spectator ions are canceled on both sides of the equation.
4. Final Net Ionic Equation: only shows active ions and the ppt.
Write chemical, complete ionic, and net ionic equations for the following.
1.
Solutions of silver nitrate and sodium chloride are
mixed.
2. Solutions of lithium phosphate and copper II sulfate
are mixed.
3.
Solutions of aluminum chloride and ammonium
hydroxide are mixed.
4.
Solutions of iron II sulfate and barium carbonate
are mixed.
5. Solutions of zinc nitrate and ammonium sulfide are
mixed.
