in a jug of copper sulphate
there are to metal's
1 pure and d other unpure
then
in the pure end (called cathide)
gathers all the copper
then all there ids is sulphate
bubbles appear

∙ 13y agoAlright, I will explain on the assumption that you know the parts needed in electroplating. You need to have the following:
- An electrode made of pure copper
- The material you want to coat with the copper
- A solution of Copper (II) ions.(Usually Copper (II) Sulfate).
Simply put the pure copper electrode as the anode(where oxidation of Cu occurs to form Cu2+ ions). And put the material you want to coat as the cathode (where reduction of Cu2+ ions will occur on the surface to form Cu metal). The solution of Cu2+ ions exist just to mediate the transfer of the ions from the anode to the cathode. Now, pass electricity through the set-up in the right direction(+ in cathode, - in anode). In the anode, Copper will oxidize to form Cu2+ ions, which dissolve in the solution. In the cathode, these Cu2+ ions will reduce to form Cu atoms on the surface of the material you want to coat. The concentration of Copper (II) ions in the solution remains the same because the rate at which the copper ions go into the solution from the anode is the same as the rate at which they go out of the solution to the cathode. After a few hours, the cathode will be coated with enough copper atoms. If you have any more questions, please post in my message board.

Is melting copper a exothermic process?
Endothermic Process.
A process used to plate metal on to a substance?
The key to plating metal is electrochemistry. Plating is electrodeposition. Connect the negative lead of a DC supply to the part to be plated, and connect the positive lead to an electrode in a tank of the plating solution. Stick your part in, turn on the juice, and wait for your results. The plating solution is basically a metal salt, and the metal in the metal salt is the one you're going to be plating onto your part. Yes, the part has to be super clean and free of any contaminants, but you knew that. Let's look at an example. Copper sulfate, which has CuSO4 as it's chemical formula, is in solution in the tank. The copper sulfate separates into Cu++ and SO4-- ions, which float around in solution. Your part is connected to the negative electrode. The power supply gives electrons to the copper ions that touch the part, the Cu++ ions we mentioned, and they become electrodeposited on the part as copper atoms. There are a number of different chemical compounds that can be used in electroplating. Our example was a sulfate. There are arsenides, carbonates and other chemical compounds available for use in electroplating that have the desired metal in them. Whether it's chromium, nickel, silver, gold or just about any other metal you can think of, you can plate it. Note that some precious metals are plated on with a sponge-tipped wand that is connected to a wire and then dipped in the electroplating solution. Gold is frequently plated on an object in this way because of the high cost of filling a tank with a solution of a gold salt. Wikipedia has more information, and a link is provided.
What is the word for copper turning green?
The word is "oxidation", which in the case of copper is a three-step process where the copper oxidizes to copper oxide, then to cuprous or cupric sulfide, and then to copper carbonate. Copper carbonate is the green colored copper or patina that forms over time. The old name for this green patina is "verdigris".
What element is used in electroplating and nichrome wire?
nickel!
Why does a copper vessel turn green in color in the rainy season?
An unprotected copper vessel will turn green eventually due to several chemical reactions, regardless of the environment. The wetness of the rainy season simply speeds up the chemical process. The process by which copper turns green in color is due to the slow oxidation of the copper metal into its oxides. Initially copper oxide forms (reddish), replaced by cuprous and cupric sulfide (color varies), and finally by copper carbonate (greenish). The final copper carbonate is highly resistant to corrosion and hence the vessel will remain green.
How is electroplating done?
the metal on which electroplating is to be done is taken as cathode ( negative electrode) . the metal of which electroplating is to be done is taken as anode ( positive electrode) and the salt solution of the metal of which electroplating is to be done is taken as electrolyte . example- if we want to electroplate iron with copper then iron is taken as cathode and copper is taken as anode and electrolyte is copper sulphate.Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes. This is done through the use of copper in a copper sulfate bath.
Why anode gets thinner after electroplating?
because of dissolution process that occurs for anode through electroplating process
Where is copper sulphate used?
for electroplating or wood presevative
Can gold be a copper colour?
Articles made of gold may be plated with copper ( copper electroplating ). The article will look like copper .
Why should copper sulphate solution be acidified during copper electroplating?
to transfer anode to cathode
What liquid would you use in the electroplating bath to coat zinc with copper?
copper sulphate solution
What metal gets coated during electroplating?
The metal that is the cathode gets coated during electroplating.
Do i use electroplating process in place of electrodeposition process?
YES
Is copper obtained from copper ore pure?
After the initial smelting to extract copper from the ore it still has to go through electroplating purification.
What equipment is used to refine copper?
Copper is refined in a smelter. Then once raw copper is obtained the final purification is via electroplating.
Which metal could not be used for electroplating by using an aqueous solution?
Silver
What is the process of layering a metal onto a surface?
