Apparatus Chemicals

Eye protection

Each working group requires:

Expanded polystyrene cups standing in glass beakers for stability, 4 (Note 1)

Measuring cylinder (25 cm3)

Thermometer, -10 °C to +110 °C or similar

Large bowl or bucket for collecting the residues from experiments. Do not let students put residues into sinks. (Note 2)

Copper(II) sulfate(VI) solution, 1.0 M (HARMFUL, DANGEROUS FOR THE ENVIRONMENT) 100 cm3

Powdered or finely–divided metals: iron, magnesium and zinc (HIGHLY FLAMMABLE), tin. Two spatula measures of each. (Note 3)
