What is the electrolysis of copper (II) tetraoxosulphate (VI)

It is generally known as copper sulphate, not what you wrote. What you wrote may be correct according to the IUPAC, but you should be aware of the common name for chemicals, and be able to understand what chemists mean when they write about chemic

Analysis of the Performance of the Electrodes in a Natural Gas Assisted Steam Electrolysis

Steam Electrolysis Cell Abstract The performance of solid oxide electrolysis (SOE) cells while operating in the natural gas assisted steam electrolysis (NGASE) mode was evaluated. The SOE cells used yttria-stabilized-zirconia (YSZ) as the oxygen 2–YSZ as22

Electrolytic Cells

Chlorine gas that forms on the graphite anode inserted into the bottom of this cell bubbles through the molten sodium chloride into a funnel at the top of the cell. Sodium metal that forms at the cathode floats up through the molten sodium chloride into a sodium-collecting ring, from which it is periodically drained.

Electrolysis

Electrolysis of water produces hydrogen and oxygen in a ratio of 2 to 1 respectively. 2 H 2 O(l) → 2 H 2 (g) + O 2 (g); E 0 = +1.229 V The energy efficiency of water electrolysis varies widely. The efficiency of an electrolyzer is a measure of the enthalpy contained in

The Carbon and Graphite anode

Bulygin 176 investigated further the C.D. within the pores of a graphite anode and found that electrolysis within the pores could not cause any significant destruction of the anode. In agreement with an earlier postulate 175 186 he showed that the attack was chiefly due to the chemical action of hypochlorous acid within the pores.
