Kool-Aid is an example of a mixture or solution?
Solution
To separate solids from liquids.
What is a solution?
A mixture where one substance is dissolved in another.
What is salt water classified as?
Solution
False- gases and solids can form solutions too.
Mechanical Mixture
What tool can be used to separate magnetic materials from non-magnetic ones?
What is the substance that dissolves called?
Solute

Why is orange juice with pulp not a solution?
Because it's not uniform. It is a heterogenous mixture.
What is the difference between a pure substance and a mixture?
A pure substance contains only one substance. A mixture has 2+ types of particles.
What process separates mixtures based on boiling points?
Distillation
What is the substance that does the dissolving called?
Solvent
Give one example of a household solution that is a gas in a liquid.
Explain how distillation works.
It heats a mixture to evaporate one substance, then cools it to collect the vapor.

Give one example of distillation in real life.
Purifying water or making scented oils, alcohol
Which separation method is used to separate salt water from fresh water?
Distillation
What type of mixture is orange juice with pulp?
Heterogenous mixture.
What method separates substances based on how they move through paper or another material?
Chromatography
What do we call a solution that cannot dissolve any more solute?
Saturated Solution
Give an example of magnetism from real life.
Recycling, glass production, food processing
Give an example of a dilute solution and a concentrated solution. Explain how you could tell the difference between the two.
