Apparatus Chemicals

Eye protection

Each group of students will require:

Beaker (250 cm3)

Graphite electrodes (about 5 mm diameter), 2

Retort stand and clamp to hold electrodes (Note 1)

DC power supply (6 volt)

Light bulb (small, 6 volt, 5 watt) – optional (Note 2)

Leads and crocodile clips

Aqueous copper(II) sulfate, about 0.5 M, 200 cm3

Copper strips (optional), 2 (Note 3)

Small pieces of emery paper

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

 






In this experiment you will carry out the electrolysis of copper(II) sulfate solution. The outcomes of the experiment link well with the industrial electrolytic refining of copper.
