- Quantitative electrolysis of aqueous copper (II) sulfate
Electrolysis of Copper sulfate (CuSO 4) Solution. Copper sulfate is soluble in water and gives a blue colour aqueous solution though anhydrous copper sulfate solid is white. In an aqueous solution, Copper sulfate completely dissociates to copper 2+ (Cu 2+) cation and sulfate (SO 4 2-) anion.
Place two graphite rods into the copper sulfate solution. Attach one electrode to the negative terminal of a dc supply, and the other electrode to the positive terminal.
