1. The separation of a mixture of insoluble solids Critical Question: How can a mixture of two solids that are insoluble in water be separated?

2. Procedure 1)Pour the mixture in a shallow pan and add water. 2) Skim floaters with filter paper. 3) Filter water and “no floaters” with a second piece of filter paper. 4)Record observations.

3. Data Observations; Filter paper one- Filter paper two-

4. Question In what characteristic property must the two solids differ in order for them to be separated by this method?

5. Conclusion
