Net Ionic Equation
A simplified chemical equation that only shows the ions that participate in the reaction, removing spectator ions.
Spectator Ions
Ions that do not change during a reaction and appear on both sides of the equation.
Steps to Writing a Net Ionic Equation
Write the full balanced equation. 2. Break all aqueous (aq) compounds into ions. 3. Identify and remove spectator ions. 4. Write the remaining reacting ions as the net ionic equation.
Complete Ionic Equation
An equation that shows all of the ions present in the reaction, including spectator ions.
Example of a Net Ionic Equation for AgNO₃ + NaCl
Ag⁺ (aq) + Cl⁻ (aq) → AgCl (s)
Why Use Net Ionic Equations?
Simplifies reactions by removing unnecessary ions. 2. Helps predict precipitate formation. 3. Shows how ions interact in solution.
Spectator Ions in AgNO₃ + NaCl
Na⁺ (aq) and NO₃⁻ (aq), because they appear on both sides and don’t participate in the reaction.
Example of a Full Reaction (AgNO₃ + NaCl)
AgNO₃ (aq) + NaCl (aq) → AgCl (s) + NaNO₃ (aq)
