What are solutions?
Solutions are two or more substances that cannot be separated.
What are mixtures?
Mixtures are two or more substances that can be separated.
Mixtures and Solutions are the same
(Explain to support your answer)
False they are not the same.
What is density?
weight per volume

solvent (water)
What are the two things that create a solution?
(Tell us what they do)
They are solutes and solvents.
Why can mixtures be separated?
They can be separated by the differences in their physical properties.
Solutions do not need a solvent
False
Something that dissolves into a liquid to create and solution
It is a solute

10-15 grams
Define a solvent
A solvent is what a solute needs to dissolve into.
Why are you able to layer some solutions?

Summarize the part about solutions
Solutions cannot be separated and can contain anything that is a solute and solvent.
Summarize mixtures
Mixtures can be separated and are created by pure substances.
