WebAug 25, 2024 · Electrolysis can also be used to drive the thermodynamically nonspontaneous decomposition of water into its constituent elements: H 2 and O 2.However, because pure water is a very poor electrical conductor, a small amount of an ionic solute (such as H 2 SO 4 or Na 2 SO 4) must first be added to increase its electrical … WebAug 14, 2024 · Figure 17.7.3: The Electrolysis of Water. Applying an external potential of about 1.7–1.9 V to two inert electrodes immersed in an aqueous solution of an electrolyte such as H 2 SO 4 or Na 2 SO 4 drives the thermodynamically nonspontaneous decomposition of water into H 2 at the cathode and O 2 at the anode.

WebSolution. In this process of electrolysis, CuSO4 solution is electrolysed in the presence of Cu electrodes. Thus, at cathode, Cu2+ will get reduced to Cu and at anode Cu will get oxidised to Cu2+. Therefore, Copper will get deposited at cathode and copper will get dissolved at anode. Hence, the correct options are (a) and (b). Web(i) Copper will deposit at the cathode. (ii) Copper will dissolve at the anode. (iii) Oxygen will be released at anode. (iv) Copper will deposit at the anode. Correct Answers: (i) Copper …
