Apparatus Chemicals

Eye protection

Each group of students will require:

Polystyrene cup or cups (Note 1)

Beaker (250 cm3) to stand the polystyrene cup in for support

Measuring cylinder (25 cm3), 4

Thermometer (-10 – 110˚C, or similar)

Spatula

Absorbent paper

Each group of students will also require access to:

Hydrochloric acid, approximately 2 M (IRRITANT) (Note 2)

Powdered or finely-divided metals: magnesium, zinc, iron, copper (ALL HIGHLY FLAMMABLE) (Notes 3 and 4)

Large bowl for collecting the waste residues from the experiments (Note 5)

For the additional teacher-only demonstration the teacher will require:

Set of apparatus and chemicals as above

Aluminium powder (HIGHLY FLAMMABLE) (Note 3)

Refer to Health & Safety and Technical notes section below for additional information.
