1. Double Replacement Reactions
When 2 ionic solutions are mixed, a double replacement reaction takes place
AB + CD  AD + CB
A and C are + cations
B and D are - anions

2. It will not dissolve in water
Based on the DRR you can identify the precipitate(s) that is formed (use the chart)
Precipitate is Insoluble
It will not dissolve in water

3. iron III chloride (aq) + potassium hydroxide (aq)
Given these reactants what will the products be?
Balance the reaction
Identify the precipitate
Net ionic?
Spectators?

4. FeCl3 + 3 KOH  Fe(OH)3 ↓ + 3 KCl Net ionic: Fe+3 + 3 OH-1  Fe(OH)3
iron III chloride + potassium hydroxide  iron III hydroxide + potassium chloride
FeCl KOH  Fe(OH)3 ↓ + 3 KCl
Net ionic: Fe OH-1  Fe(OH)3
Spectator ions : K+1 + Cl-1

5. magnesium nitrate (aq) + ammonium hydroxide (aq)
Products?
Balance.
Precipitate?
Net ionic?
Spectator ions?

6. Net ionic: Mg+2 + 2 OH-1  Mg(OH)2 Spectator ions: NH4+ & NO3-1
magnesium nitrate + ammonium hydroxide 
magnesium hydroxide + ammonium nitrate
Mg(NO3) NH4OH  Mg(OH)2↓ NH4NO3
Net ionic: Mg OH-1  Mg(OH)2
Spectator ions: NH4+ & NO3-1
