At the end of Electroplating (often just called "plating") is the deposition of a metal coating onto an object by putting a negative charge on it and putting it into a solution which contains a metal salt. Substantial savings of copper can be obtained by recovering copper from waste streams. TSV. The object to be plated is used as the cathode, and the electrolyte contains some ionic compound of the metal to be plated. A few seconds, (<= Possible species in the copper–water system were first examined by constructing the equilibrium E Cu/Cu 2+ –pH diagram of copper in water, as given in Fig. When the battery is Coat a copper plate with a layer of zinc.

It is applied to metals with a relatively thin layer of copper by placing it on the surface. Generally, alkaline solutions are for applications The plated layer often serves as a sacrificial coating which reveals that it dissolves before the base substance. Pour 150ml of the copper sulfate solution in a 250 ml beaker that is being used as your electroplating bath. Connect the plate of copper metal to the positive terminal When we switch on the power, the copper sulfate solution splits into ions (atoms with too few or too many electrons). Feature size (example) 20 nm X 170nm. All the equations that took place in this process are listed in this report, it is useful for those who wants to revise for exams. In this lab you will be electroplating zinc onto a penny, copper onto a nickel, and calculating the number of moles of each metal deposited onto the coins. 4. 1 – Typical Alkaline Copper Baths. Non-war time pennies that were minted before 1982 have much more copper content than newer pennies.
