1. CC1/2 – States of Matter and Mixtures (p97-104)
Fractional distillation – fill in the gaps
A fractionating column is fitted above a mixture, with several condensers coming off at different ________. The column is ______ at the bottom and _____at the top. Substances with ____ ________ points ________ at the bottom and substances with _______ __________points condense on the way to the ______.
Heating curves – what is happening at points a, b, c, d, and e? Add particle diagrams for each section.
CC1/2 – States of Matter and Mixtures (p97-104)
Changing state - annotate the arrows with a key term and description
Boiling point and melting Point - What state would this element be in at room temperature?
BP = 150oC, MP = -23oC
Pure substances or mixtures? – explain how you can tell
Core practical: chromatography - annotate the chromatogram with everything you can tell from it (including Rf values)
Core practical: distillation of inky water – label the equipment to show what happens in each part
Clean water – explain the stages in producing water which is safe to drink

2. CC1/2 – States of Matter and Mixtures (p97-104)
Fractional distillation – fill in the gaps
A fractionating column is fitted above a mixture, with several condensers coming off at different heights. The column is hot at the bottom and cooler at the top. Substances with high boiling points condense at the bottom and substances with low boiling points condense on the way to the top.
Heating curves – what is happening at points a, b, c, d, and e? Add particle diagrams for each section.

Boiling point and melting Point - What state would this element be in at room temperature?
BP = 150oC, MP = -23oC
Pure substances or mixtures? – explain how you can tell
Core practical: chromatography - annotate the chromatogram with everything you can tell from it (including Rf values)
Mixture – 2 different substances, 1 atom and 1 molecule
Pure – 1 type of atom
Liquid, has melted but not boiled
Pure – 1 type of compound
Mixture – 2 different compounds
Core practical: distillation of inky water – label the equipment to show what happens in
each part
Clean water – explain the stages in producing water which is safe to drink
Solvent front A
Thermometer – to note the boiling point
Separated chemicals unique to each mixture
Rf value = distance from pencil line to B divided by distance from pencil line to A
Liebig condenser - water out
Water vapour being cooled by condenser B
Filtration – through layers of sand and gravel to remove insoluble solids
Sedimentation – tiny solid particles clump together and settle out
Chlorination – chlorine is added to sterilise water (kill microbes)
Chemicals present in both mixtures
Liebig condenser - water in
Water vapour
Water
Solvent
Pencil line
Inky water in round bottom flask
Clean water
Blue Bunsen flame to heat the mixture
