Catalyst 2, Unit F:
Compounds and mixtures
Lesson F1: Compounds all around
Main activities
F1a Are compounds different from the elements in them?
For the class:
 four samples of powdered sulphur in sealed, transparent jars
 four samples of iron filings in sealed, transparent jars
 four magnets
For the teacher:
 wooden mallet
 two test tubes
 newspaper
 test tube rack
 forceps
 pieces of filter paper dipped into lead nitrate solution
 dilute sulphuric acid (0.4mol/dm3)
For each group:
 disposable test tube (a combustion tube) containing 0.5cm3 of an iron/sulphur mixture made
from mixing 5g of iron filings with 3g of powdered sulphur, with a plug of mineral wool
already placed in the test tube
 test tube holder
 Bunsen burner
 heatproof mat

 copper foil cut into 1cm2 piece
Or





250cm3 beaker,
enough silver nitrate (very dilute solutions, e.g. 0.05 M, work fine) to cover a loop of copper

Compounds and mixtures
Capture interest (2)
 250cm3 beaker dilute HCl or 1M sulphuric acid
 10 cm strip of clean magnesium ribbon
 10cm strip of copper foil
 crocodile clips and leads
 small bulb (1.5V)
Main activities
F2a Collecting evidence for chemical reactions
For each group:
 six test tubes
 test tube rack
 spatula
 solutions of sodium carbonate, dilute hydrochloric acid (0.4mol/dm3), silver nitrate solution,
potassium iodide solution and copper(II) sulphate
 solids: iron(II) chloride, magnesium carbonate and sucrose (sugar)
 Bunsen burner
 heatproof mat
 test tube holder
Notes on materials preparation:
0.4mol/dm3 hydrochloric acid should be prepared in a fume cupboard by making up 35cm3 of
concentrated hydrochloric acid to 1000cm3 with distilled water.
F2b Reacting ammonia with hydrogen chloride
For the teacher demonstration:
 access to a fume cupboard
 diffusion tube (preferably 1metre length)
 concentrated ammonia solution
 concentrated hydrochloric acid
 forceps/tongs
 cotton wool
 universal indicator paper
 metre rule
 two retort stands and clamps
 eye protection

Lesson F3: What’s in it?
Starter activities
Capture interest
 large glass filter funnel
 crushed ice
 salt
 long-stemmed thermometer or access to a temperature probe and datalogger
Brainstorming
You may find it useful to have dictionaries or a bank of words preprepared which pupils can then
look up to see their connection with water.
Main activities
F3a A closer look at salty water
For each pupil:
 250cm3 beaker
 two boiling tubes
 thermometer (−10 to 110°C)
 ice cubes (to be crushed)
 salt
 glass rod
 tablespoon
 pure water labelled A
 salt solution labelled B
NB: Short stirring thermometers are ideal for this activity.
F3b The effect of salt on the boiling point of water
For each group:
 boiling tube
 thermometer (−10 to 110°C)
 clamp
 Bunsen burner
 heatproof mat
 pure water labelled A
 salt solution labelled B
Notes on materials preparation:
A long thermometer is better than a short stirring thermometer for this activity.
