(s)
7
What makes a reaction likely to occur?
Driving forces
8
formation of a precipitate
Driving force for double displacement reactions
9
an insoluble solid that forms when two aqueous solutions are combined
Precipitate
explore the simulation on the next slide
10
11
Open Ended
List two observations you made after exploring the simulation
12
If the reaction occurs: some ions form the precipitate
Other ions remain unchanged in solution ("spectator ions")
Double displacement reactions
13
If no precipitate forms, no reaction will take place
All the ions just remain in solution
Double displacement reactions
14
We can use the solubility table to determine this
Will a particular ionic compound dissolve in water?
15
