Miserable Mixtures Flashcards

What is a mixture?
A mixture is two or more substances not chemically bonded.
How is a mixture different from a compound?
Mixtures can be separated by physical methods and have the properties of the substances in them. No chemical change occurs when making a mixture.
How can we use particle diagrams to represent mixtures?
Particle diagrams can visually represent the different substances in a mixture.
How are solids separated out of mixtures?
Insoluble solids can be separated by filtering the mixture. The insoluble solid cannot pass through the filter paper but the liquid can.
How can we separate a soluble solid from a liquid?
Evaporation can be used to separate a soluble solid from a liquid. The solution is heated so that the liquid evaporates, leaving the solid behind.
What is chromatography?
Chromatography is used to separate mixtures of coloured or non-coloured substances that are soluble in the same solvent.
How does chromatography work?
The substances in the mixture get separated because more soluble substances spread along the paper faster.
