Question Answer
Residue The substance left behind in a sieve or filter
Concentrated Contains a large number of solute particles in the volume of solution
Concentration How much solute is dissolved in a solvent
Crystallisation Separation technique used in conjunction with evaporation to remove a dissolved solid from a liquid; after the liquid has been evaporated the solid remains, often in the form of small crystals
Decanting Technique used to seperate a sediment from the liquid it is in by carefully pouring the liquid away
Dilute Contains a small number of solute particles in volume of solution
Dissolved A solute forms a solution
Distillation Technique that uses evaporation and condensation to seperate a solid and contaminant and the solvent in which it has dissolved
Suspension A cloudy liquid containing insoluble particles
Evaporation Change in the state from liquid to gas; also a technique used to seperate dissolved solids from water
Filtration
Filtrate The substance that passes through a filter
Insoluble Can't be dissolved in a liquid
Mixture Something made up of two or more pure substances mixed together.
Properties Characteristics or things that make something unique
Pure substance Something that only contains one type of substance.
Solution A liquid made up of a solvent with a solute dissolved in it.
Solute A substance that dissolves in a liquid (solvent).
