Apparatus Chemicals

Eye protection

Each group of students will need:

Measuring cylinder (5 or 10 cm3)

Well-plate (24 wells) – eg Sigma ref: M9655

Glass rod

Plastic dropping pipettes, 6

Potassium dichromate(VI) solution, 0.1 M (TOXIC), 2 cm3

Sulfuric acid, 1 M (IRRITANT), 1 cm3

The following alcohols in dropping pipettes:

Ethanol (HIGHLY FLAMMABLE) or Industrial denatured alcohol, IDA (HIGHLY FLAMMABLE, HARMFUL)

Propan-1-ol (HIGHLY FLAMMABLE, IRRITANT)

Propan-2-ol (HIGHLY FLAMMABLE, IRRITANT)

2-methylpropan-2-ol (HIGHLY FLAMMABLE, HARMFUL), or other tertiary alcohol

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