Unit 7 - Solution Chemistry - Honors Addendum

Question 1

Definition of Net Ionic Equation (3)

Classification, Action and Goal

Answer 1

1. Chemical Reaction of Aqueous Solution and Ions
2. Excludes Spectator Ions (to show which ions participate in rxn)
3. Predicts formation of Precipitate in Double Replacement Rxn

Question 2

Definition of Spectator Ions

Answer 2

Ions in a chemical reaction that do not undergo any change

Question 3

How do you Solve a Net Ionic Equation? (6)

Answer 3

1. Predict Products of Rxn (Double Replacement of Anions & Cations)
2. Balance Ionic Equation
3. Dissociate Ions (aq) to Cations & Anions (Insoluble Copounds (s) CANNOT Dissociate)
4. Add Charges & Phases - (aq) for dissociated Ions and (s) for insoluble compounds
5. Cross Out Spectator Ions that Dissociated & didn’t change charge/phase
6. NEVER CROSS OUT SOLID INSOLUBLE COMPOUNDS IN REACTANT
