Different kinds of mixture: suspension, colloid, solution
Suspension= solid particles spread out through the mixture without dissolving e.g. muddy water
Colloid = mixture that looks cloudy or opaque e.g. milk. Particles of solids are smaller
Solution: the solids break up into such small pieces that you can't see them, the mixture is transparent
Soluble: Substances that can be dissolved in solvents.
Solute: A substance that is dissolved in a solvent.
Solvent: A liquid that can dissolve a substance.
Some gases can dissolve in water
Concentration: the amount of solute dissolved in a solvent
Saturated: when no more solute can dissolve in a solvent
What is filtering used for?
to seperate solids from a suspension
What is evaporation used for?
to seperate solids from a solution or colloid
What is distillation used for?
Separating liquids from mixtures.
What is chromatography used for?
to separate individual solutes from a mixture of solutes in a solvent
