But it’s actually reacted with the sulfuric acid and made the solution blue. This is copper sulfate solution. Once we see unreacted copper oxide in the beaker…we know that all of the acid has ...

To grow pure metal crystals, he used copper wire and copper sulfate. He also used a special regulated power supply to create a low voltage to control the current used to form the crystal.

The Cu POX process is a proven hydrometallurgical method for the treatment of copper sulfide concentrates at lower capacities.

[A_Steingrube] is using the copper acetate method of plating. What is somewhat novel about his method is that he chose to make his own electrolyte solution from household chemicals. The copper ...

Using a copper sulfate solution, we can etch glass with a pulsed laser like the relatively common Nd:YAG fiber lasers. The CuSO4 solution absorbs laser pulses, vaporizes and forms copper oxide on ...
