Mixtures 1.1.2 Flashcards
What are mixtures formed from?
Two or more substances that have not been chemically bonded.
Crystallisation splits…
Solutes and Solvents.
Crystallisation can be conducted by…
Evaporating a solution,
Condensing the solvent vapour,
Collecting it in a different container.
Chromatography splits mixtures into…
Multiple solutes and one solvent.
Chromatography can be conducted by…
Placing solution at bottom of Ch. paper,
Dipping paper in solvent.
Solutes travel up the paper at different levels.
Filtration separates…
Insoluble solids and liquids.
Filtration can be conducted by…
Placing mixture on to filter paper,
Liquid filtrate runs through the paper,
Solid residue is left behind.
Simple distillation separates…
Two liquids with different boiling points.
In Simple Distillation, separation occurs because…
One liquid will boil before the other.
In Fractional Distillation, separation occurs, because…
The temperature slowly increases, boiling one liquid at a time until all liquids have boiled.
What is a solvent?
A liquid in a mixture.
What is a solute?
A solid in a liquid.
