What you can learn
- A precipitate forms when two ions combine into an insoluble compound.
- Solubility rules tell you which combinations stay dissolved.
- The net ionic equation shows only the ions that actually form the solid.
Frequently asked questions
What is a precipitate?
An insoluble solid that forms when two solutions are mixed. It appears as cloudiness or solid settling out.
What are spectator ions?
Ions that stay dissolved and do not take part in forming the solid. They are left out of the net ionic equation.
