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 H2O
• Use solubility table
• Write in ion form

4

• Steps for writing net ionic eqns
• 1. Write molecular eqn, (Dont 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 (CH4) is burned in air.
• 1 Molecular eqn
• 2 Ionic
• 3 Net ionic eqn
