Explain the process of electroplating of copper?

Answer 1

metal ions form a solid layer on a metal cathode

Answer 2

Electroplating of copper involves passing an electric current through a copper salt solution, which contains copper ions. The copper ions are attracted to the object being plated (cathode) and deposit onto its surface, forming a thin layer of copper. The object to be plated and a copper anode are immersed in the solution, and as the current passes through, copper from the anode dissolves into the solution to replenish the copper ions.

Answer 3

its a method of separating with pure and unpure metal

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

Answer 4

Alright, 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.

Answer 5

it is attached to negative terminals of the electric source it takes on the color of metal being plated and then is placed in an electroplating solution and then gains weight

Answer 6

Electroplating uses electrical currents to reduce dissolved metal cations. This is done to form a coherent metal coating on an electrode and change the surface properties of an object.

Answer 7

Metal Ions form a solid layer

Answer 8
