Question #
Answer
1
1. Solution
2. Suspension
3. Colloid
4. Suspension
5. Colloid
6. Solution
7. Solution
8. Colloid
9. Suspension
2
* 2 or more substances
* Same phase
* Even throughout
3
* 2 or more substances
* Different phases
* Scatters light
4
When suspensions are mixing around, there will be a Tyndall effect. Once the mixing stops and the substances have settled, there is no Tyndall effect
5
The particles in a colloid DO NOT settle. Suspensions DO settle (i.e density layers).
