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.

Copper oxide thin films, particularly cupric oxide (CuO) and cuprous oxide (Cu2O), have garnered significant attention in recent years due to their versatile applications in fields such as ...

In this reaction, we are going to use sulfuric acid and copper(II) oxide. This time there will be no gas produced. However, there will be other evidence that a chemical reaction is taking place.

The record efficiency was achieved by engineering the cell with reduced copper(II) oxide (CuO) and copper (Cu) impurities in the thin-film deposition. It showed an open-circuit voltage of 1.13 V ...
