What makes a reaction likely to occur?

​

​Driving forces

8

media

formation of a precipitate

​

​Driving force for double displacement reactions

9

media

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

media

If the reaction occurs: some ions form the precipitate

Other ions remain unchanged in solution ("spectator ions")

​

​Double displacement reactions

13

media

If no precipitate forms, no reaction will take place

All the ions just remain in solution

​

​Double displacement reactions

14

media

We can use the solubility table to determine this
