Copper is used in the construction of electrodes because it is a good conductor of electricity, corrosion resistant, and malleable. These properties make it ideal for carrying electrical current and withstanding the chemical reactions that occur during electrode processes.
Ni2+
Yes, a cell with copper and zinc electrodes in an acid electrolyte will produce voltage because of the difference in their reduction potentials. The zinc will undergo oxidation at the anode, releasing electrons and creating a potential difference with the copper cathode where reduction occurs. This potential difference between the two electrodes generates an electric current.
In an electrolytic cell with nickel and copper electrodes, nickel at the anode gets oxidized, losing electrons to form nickel ions. The copper electrode at the cathode gains electrons and gets reduced, forming copper metal. This process allows for the transfer of nickel ions from the anode to the cathode.
The reaction equation for the electrolysis of water using copper electrodes is: 2H2O(l) -> 2H2(g) + O2(g). At the cathode, hydrogen gas is produced, while at the anode, oxygen gas is produced. Copper electrodes do not participate in the reaction, they only serve as conductors for the flow of electrons.
Cu(s)
Inez used a zinc nail and copper penny as electrodes in her science project.
Inert electrodes simply serve as electrical conductors and are unchanged by the cell processes. Active electrodes change during the cell reactions. An example of inert electrodes is platinum in the electrolysis of water. The platinum remains unchanged and the water is split into hydrogen and oxygen. An example of active electrodes is in the electrolysis of copper sulfate solution with copper electrodes. The anode copper is converted into copper ions in the solution, and metallic copper builds up on the cathode. The term active electrode is also used in eeg measurement, here as the opposite to passive electrode. Electrodes are the pads attached to the skin to get readings, and active ones don't need a conductive paste to get a good signal.
Various elements are used for making electrodes like copper, zinc, aluminium, chlorine, mercury, platinum etc. Elements for making electrodes are selected on the basis on their relative tendencies to gain and loose electrons.
Electrolysis
Factors that can affect the electrolysis of molten copper chloride include the current applied, the concentration of copper ions in the electrolyte, the temperature of the electrolyte, and the composition of the electrodes used in the electrolysis process. Additionally, factors such as the purity of the copper chloride and the presence of impurities in the electrolyte can also impact the efficiency of the electrolysis process.

i am not entirely sure what this process is called, but i do know how you do it! you put in two electrodes with a solution of it into a beaker, make sure the electrodes are not touching, then send a current through them and the chlorine will bubble around one of the electrodes and the copper will be wrapped around the other, this is because of the charges in the copper and the chlorine, i can't remember which one is negatively charged and which is postively charged.

For copper, you can substitute with graphite electrodes which are commonly used in electrochemistry applications. For zinc, you can consider using magnesium electrodes as they are also commonly employed in electrochemical processes as a sacrificial anode. Always ensure compatibility with the specific electrolyte and application conditions.

Yes, a cell with copper and zinc electrodes in an acid electrolyte will produce voltage because of the difference in their reduction potentials. The zinc will undergo oxidation at the anode, releasing electrons and creating a potential difference with the copper cathode where reduction occurs. This potential difference between the two electrodes generates an electric current.
Because sulphate ions move towards anode (copper) the copper of anode donates 2 electrons to external circuit and becomes +2 ions and moves to the solution so copper anode continuously dissolves in solution.
