Definitions
This is the substance that gets dissolved.
What is a solute?
A solution with a lot of solute compared to solvent.
What is concentrated?
Sugar in water: soluble or insoluble?
What is soluble?
This method separates colors or substances by letting them move across special paper at different speeds (e.g., the colour black).
What is paper chromatography?
This method separates an insoluble solid from a liquid using filter paper or a strainer (e.g., coffee maker).
What is filtration?
The substance that does the dissolving.
What is a solvent?
A solution with very little solute compared to solvent.
What is diluted?
Sand in water: soluble or insoluble?
What is insoluble?
This is the process where solvent particles leave while the solute particles remain (e.g., sugar water or maple syrup).
What is evaporation?
This technique separates substances based on appearance (e.g., recycling paper from plastic).
What is sorting?
A mixture where a solute dissolves evenly in a solvent.
What is a solution?
A solution that can still dissolve more solute.
What is unsaturated?
Pepper in water: soluble or insoluble?
What is insoluble?
This technique separates liquids by heating them into vapor and then cooling them back into liquid. It allows us to keep both the solute and solvent (e.g., perfume or gasoline).
What is distillation?
This method separates solids by component size (e.g., separating gravel from sand).
What is sifting?
A substance that cannot dissolve in a solvent.
What is insoluble?
What is a mechanical mixture?
Salt in water: soluble or insoluble?
What is soluble?
This happens when a substance that is less dense rises to the surface of a liquid (e.g., fat from chicken broth).
What is floating?
This technique separates magnetic materials from non-magnetic ones using a magnet (e.g., iron from sand pellets).
What is magnetism?
The amount of solute that can dissolve in a solvent at a given temperature.
What is solubility?
Is a mixture of 2+ substances you cannot see.
What is a solution?
Oil in water: soluble or insoluble?
What is insoluble?
This occurs when heavier particles sink to the bottom of a mixture due to higher density (e.g., blood).
What is settling?
This technique occurs when one part of a mixture dissolves easily in a solvent (e.g., separating sand from salt water).
