2. IONIC and NET IONIC EQUATIONS Net ionic – an equation representing what happens to the ions in a reaction - shows what is really taking place in a reaction

3. Aqueous substances –soluble in H 2 O –Use solubility table –Write in ion form

4. Steps for writing net ionic eqns: –1. Write molecular eqn, (Don’t balance) –2. Write ionic eqn – use solubility table –3. Write net ionic eqn – cancel spectator ions Spectator ion – an ion that does not change from reactant side to product side

5. Example #1 – Sodium chloride reacts with lead (II) nitrate to form sodium nitrate and lead (II) chloride 1 – Molecular eqn 2 – Ionic 3 – Net ionic eqn

6. Example #2 – Solutions of barium bromide and sodium sulfate react together. Predict the products, write the net ionic eqn. 1 – Molecular eqn 2 – Ionic 3 – Net ionic eqn

7. IMPORTANT: Compounds that are _________ according to the _________ can ________ into _____ ONLY if __________ is present.

8. Example #3 – Sodium chlorate decomposes. 1 – Molecular eqn 2 – Ionic 3 – Net ionic eqn

9. Example #4 – Methane gas (CH 4 ) is burned in air. 1 – Molecular eqn 2 – Ionic 3 – Net ionic eqn
