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.

What electrode is more reactive copper or zinc?
Zinc
How does Daniell cell produce electricity?
In a Daniell cell, a chemical reaction occurs between zinc and copper in separate compartments connected by a salt bridge. The zinc undergoes oxidation, releasing electrons, which flow through an external circuit to the copper, where reduction occurs. This electron flow generates an electric current.
In volta's battery a chemical reaction between which two metals produced a current?
In Volta's battery, the chemical reaction occurs between zinc and copper, which produces a current through the flow of electrons from the zinc to the copper electrode. This reaction is driven by the difference in electronegativity between the two metals.
Does zinc usually combine with copper?
Alloys of zinc and copper are well known. There are no chemical compounds of zinc and copper.
Does copper displace zinc from zinc sulphate?
No, zinc will displace copper from copper sulphate but not the other way around.
What electrode is more reactive copper or zinc?
Zinc
Describe the functioning of copper zinc electrochemical cell?
In a copper-zinc electrochemical cell, oxidation occurs at the zinc electrode, leading to the release of electrons and zinc ions. The electrons flow through the external circuit to the copper electrode, where reduction occurs, resulting in the deposition of copper metal. This flow of electrons creates an electric current that can be harnessed for various applications.
Why does zinc and copper create a higher voltage than copper and copper in a circuit?
Zinc has a greater tendency to lose electrons compared to copper, making it a better anode. When paired with copper in a circuit, zinc undergoes oxidation and produces electrons that flow to the copper cathode, generating a higher voltage due to the difference in their electrode potentials. This difference in electrode potentials creates a potential difference and drives the flow of electrons, resulting in a higher voltage compared to a copper-copper circuit.
Why do zinc and copper work well together to generate energy?
Zinc and copper work well together in a galvanic cell because zinc readily loses electrons while copper readily gains electrons. This difference in reactivity leads to the flow of electrons from the zinc electrode to the copper electrode, creating an electrical current that can be harnessed as energy.
How do you use electrode in a sentence?
Inez used a zinc nail and copper penny as electrodes in her science project.
What will happen when electrolysis of dilute sodium chloride solution using copper and zinc electrode?
When electrolysis is performed on a dilute sodium chloride solution using copper and zinc electrodes, chlorine gas will be produced at the anode (positive electrode) and hydrogen gas will be produced at the cathode (negative electrode). At the same time, sodium hydroxide solution will be formed in the solution. The copper electrode will remain unaffected, while the zinc electrode may corrode due to hydrogen evolution reactions.
If zinc electrode is dipped in zinc sulphate the electrode will become positive or negative?
if it is dipped the zinc electrode looses the electron in to the solution as zinc ions and it attains negative charge on th electrode and it absorb the positive ions in the solution.so w can see a bundle of positive ions just around the zinc electrode
What happen when zinc and copper in salt water?
When zinc and copper are placed in salt water, an electrolytic cell is formed. The zinc will undergo oxidation at the anode, releasing electrons into the circuit. These electrons flow to the copper electrode (cathode), where reduction occurs. This flow of electrons generates an electric current.
Why does hydrogen gas liberate at Cu electrode in Zn-Cu cell?
In a Zn-Cu cell, zinc is more reactive than copper. When the cell operates, zinc atoms lose electrons at the anode (Zn electrode) to form Zn2+ ions. These electrons flow through the external circuit to the cathode (Cu electrode) where they are used to reduce Cu2+ ions back to copper atoms, liberating hydrogen gas as a byproduct at the Cu electrode.
How does Daniell cell produce electricity?
In a Daniell cell, a chemical reaction occurs between zinc and copper in separate compartments connected by a salt bridge. The zinc undergoes oxidation, releasing electrons, which flow through an external circuit to the copper, where reduction occurs. This electron flow generates an electric current.
Will a copper and a zinc electrode placed in an acid solution create a current?
yes, in fact they are used for a type of Voltaic battery.
Which combination of metals do you think will give the highest voltage copper and lead or zinc and lead?
The combination of zinc and lead will generate a higher voltage compared to copper and lead. This is because zinc is more electronegative than copper, leading to a greater difference in their electrode potentials and a higher voltage output.
