Answers vary

300

What happens to the properties of substances in a mixture compared to the properties in a solution?

mixtures: keep physical properties 

solution: one dissolves in the other solution

Answers Vary 

500

If you were designing a science experiment with mixtures and solutions, what steps would you take to test whether a mixture is also a solution?

Mixture: keep their physical properties & you can separate 

Solution: One dissolves
