Figure 7 shows the general arrangement with the power pack and large ammeter to the right, and the cell with the cathode in the middle of the picture. Just to the left is the anode sample attached to the polystyrene raft. To the left again are the ballast power resistors for use at very low current levels, and behind is a 500gm tub of copper sulphate and the 500m1 of Lascaux resist.
Figure 7
A saturated solution of copper sulphate crystals, (CuSO4) is 250gm/litre of water. I made up a 1:3 solution by dissolving 42gm in 500ml of distilled water. It is sensible to use plastic gloves, as the solution can dry the skin and leave a long-lasting blue tinge under finger nails.
