Substances Change When Forming Solutions
Analyze
5. How do you know when a solution forms?
6. How could you prove that the powdered
drink mix and the alcohol are still present in
the solution?
7. Would you classify powdered drink mix as a
soluble or insoluble in water? Explain.
8. What would you classify alcohol? Explain.
