Techniques for Copper Plating with Copper Sulfate Solution

Techniques using the process of copper plating with a copper sulfate solution relate to choosing an ideal water to copper sulfate ratio The amount of copper sulfate in the solution is limited by the water saturation capacity so once the solution is mixed in and the water no longer causes it to dissolve and instead causes it to settle to the bottom of the vessel maximum saturation has been
