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.
Why do electrons only travel in one direction in voltaic cells?
The electrode potential or the reduction potential of zinc is less than that of copper. Therefore, zinc loses the electrons and copper ions gain them forming solid copper and producing electricity. Copper is not able to loose electrons due to presence of zinc and hence electrons flow in one direction only.
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.

How do you use electrode in a sentence?
Inez used a zinc nail and copper penny as electrodes in her science project.
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
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.
How do you make a bulb light with a with a fruit?
First, get a zinc electrode and a copper electrode. You can use a zinc coated nail and a penny. Put both of them into the fruit. You might need lots of fruit. Attach them together (in series), copper to zinc, and vice versa. The electrodes of the same fruit can't be wired together. Attach the free ends of the wires to the light, and it should light up!
What is a synonym for electrode?
According to Thesaurus.com synonyms: copper cathode, inert anode, inert cathode,plate, wire, zinc anode

What it the alloy of copper an zinc?
Alloys that contain only copper and zinc are usually called "brass"; there are also some alloys that contain one or more other metals in addition to copper and zinc, and these usually have another name.
What is a sentence for zinc?
The negative electrode of a dry cell battery was made of zinc.
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.
Does zinc usually combine with copper?
Alloys of zinc and copper are well known. There are no chemical compounds of zinc and copper.
