This outlines one way to carry out the practical using copper(II) oxide powder and dilute sulfuric acid. Eye protection must be worn. 1. Add some dilute sulfuric acid to a small beaker.

The etching solution eventually becomes saturated with copper (II) oxide, which starts precipitating out of the solution as a blue-green solid. It takes a while to get there, though; depending on ...

Using a combination of experiments and computer simulations, scientists now understand how oxygen affects the way the catalyst copper oxide (CuO ... Light Source II, both of which are DOE Office ...
