(4) \(Cu\ +\ H_2SO_4\ +\ H_2O_2\ \to\ CuSO_{\text{4}}\ +\ 2H_2O\)\cite{Mlasi_2015}
In order to store the CuSO4 for future laboratory use, it should be converted to CuSO4.5H2O or copper (II) sulfate pentahydrate, through dehydration.
Due to the constraints of finances and resources, rather than purchasing a membrane electrolysis system, one was constructed using three 20 micron pore size filter papers secured in a PVC pipe end.
2.2 Membrane Electrolysis Apparatus Construction
The membrane electrolysis apparatus was constructed using an 11cm long 3.4cm outer diameter schedule 40 PVC pipe, 3.4cm inner diameter PVC coupling, 1mm diameter galvanized steel wire, a 200ml beaker, two 10cm 0.5cm diameter graphite electrodes, two Frey Scientific-584283 platinum electrodes, three 20 micron pore size filter papers, and heat shrink electrical wrap tubes.
The PVC coupling was cut on both connector ends with a PVC pipe cutter, to create two 0.5cm long rings. Place one of the coupling rings 3.8cm from one of the ends (to be referred to as the top end) of the 11cm PVC pipe. On the other end (to be referred to as the bottom end) of the PVC pipe, three filter papers were placed covering the end. The second coupling ring was forced over the filter paper so that it secured the filter papers in place. A 20cm piece of galvanized steel wire was placed around the coupling closest to the top end so that it was further from the top-end than the ring and wrapped around the PVC pipe to make 3 legs 120 degrees apart. (See fig. 1) These legs were bent over the rim of the 200ml beaker. (See fig. 2)
