When aqueous copper sulphate solution is, electrolyzed, the following redox reactions are possible. If you remove electrons from sulfa. Copper sulfate solution (CuSO4 (aq)) contains the following ions: At the anode: 2O2- -2e- → ↑O2 (g) - oxygen ions lose electrons to become oxygen gas. It must be right. Electrolysing. This time you can't start by working out the number of coulombs, because you don't know the time. (2006, 2011) ii) electricity is passed through molten/fused lead bromide. Copper sulphate solution is ionised by the following chemical equation: CuSO 4 → Cu 2 . Answer (1 of 4): Clearly there is no water present in a melt like this so hydrogen is ruled out. Using a retort stand and clamp is probably the most convenient. This time you can't start by working out the number of coulombs, because you don't know the time. Science Advisor.

We can purify a solution containing copper, such as copper (II) sulphate, using electrolysis. using active electrodes) results in transfer of copper metal from the anode to the cathode during electrolysis. The picture shows electrolysis of copper(II) sulphate solution using graphite electrodes. There are tiny concentrations of hydrogen ions H + and hydroxide ions (OH -) from the self-ionisation of water itself, but these can be ignored in this experiment. Write equations for the reactions taking place at the two electrodes (mentioning clearly the name of the electrode) during the electrolysis of: i) Acidified copper sulphate solution with copper electrodes. Therefore the anode decreases in size and the impurities fall to the bottom of the cell.
