phate is CuS04 and by electrolysis it isI separated into Cu (metallic copper)~^W and S04 (sulphion). The hydrogenFig. 95--^e°tPPer Volta gas liberated at the negative plate dis-places the Cu of the CuS04 formingH2S04 (sulphuric acid), and deposes the Cu on the negativeplate, while oxygen gas is… … ELECTROLYSIS. 81 as before. If the action is allowed to continue for some tir^all the metallic copper is taken from the solution and deposed.This will be noted by the solution changing from a deep to apale blue, as the change gradually takes place from coppeisulphate to sulphuric acid.
