In the 1.0 M CUSO4 solution, the following species are present: Cu²+, SO42, H₂O, H3O+, and OH. Based on observed changes that occurred in each electrode, write the RHR, OHR, and the balanced overall reaction of electrolytic cell. The reactions should be consistent with the observations. For this part, refer to the following Setups: Electrodes Solution Current Time For the experimental data: Anode Carbon Setup 1 Initial mass of anode (g) Initial appearance of anode Final mass of anode (g) Observations at the anode Cathode Carbon 1.0 M CuSO4 1.50 A 20.00 minutes Table 8b-1.
