What electrode is more reactive copper or zinc?
Zinc
How does Daniell cell produce electricity?
A daniell cell is a system comprising a copper container, a solution of copper ions, a porous pot, a solution of zinc ions and a zinc rod. When the zinc rod and the copper container are connected by a wire, the zinc rod is oxidised to zinc 2+ ions, which releases two moles of electrons per mole of zinc decayed. These electrons flow round the wire to the positive electrode, the zinc container, where the copper ions in the solution are reduced to copper metal. If components eg. A light bulb, are placed within the circuit, the electron flow from the zinc to the copper electrode will power the bulb.
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 copper displace zinc from zinc sulphate?
No, zinc will displace copper from copper sulphate but not the other way around.
Does zinc usually combine with copper?
Alloys of zinc and copper are well known. There are no chemical compounds of zinc and copper.
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?
It is very weird and I am gonna help. Zinc and copper create a higher voltage than copper and copper because zinc has a higher voltage than copper so copper plus zinc equals more than copper plus copper.
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?
Usually hydrogen will evolve from the cathode and oxygen from the anode, but if zinc is the anode, it may dissolve to produce zinc ions in the solution either instead of or along with oxygen evolving.
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 zinc-copper cell, zinc gives up electrons, forming the negative terminal of the cell, and the electrons flows as electric current through wires. When the electrons reach the other positive terminal, electrolysis of the electrolyte takes place at the positive terminal. Hydrogen ions and the cation of the electrolyte will be attracted to the positive Copper electrode. The hydrogen ions, being less reactive than the cation ions, will take up the electrons on the copper electrode, forming hydrogen gas.
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.
