Apparatus Chemicals

Eye protection

Each student or pair of students requires:

Comboplate®, 1 (Note 1)

Syringe (2 cm3)

Lid number 1

Lid number 2

Short lengths silicone tubing, 2

Piece of glass tubing (10 cm) – of a width to match the silicone tubing

Matches

If students are calculating percentage yield, they also need access to a balance which reads to two decimal places.

Copper(II) oxide (HARMFUL, DANGEROUS FOR THE ENVIRONMENT), ~ 0.5 g

Magnesium ribbon, 3 cm

Dilute hydrochloric acid, 2 M (IRRITANT), about 2 cm3

Microburner filled with ethanol (HIGHLY FLAMMABLE), or Industrial Denatured Alcohol, IDA (HIGHLY FLAMMABLE, HARMFUL) (Note 2)

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

ADDITIONAL INFORMATION

This is a resource from the Practical Chemistry project, developed by the Nuffield Foundation and the Royal Society of Chemistry. This collection of over 200 practical activities demonstrates a wide range of chemical concepts and processes. Each activity contains comprehensive information for teachers and technicians, including full technical notes and step-by-step procedures. Practical Chemistry activities accompany Practical Physics and Practical Biology.
