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.

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.

Drill results include 10.69% copper over 21 metres, 5.60% copper over 26 metres, and 3.01% copper over 15 metresVancouver, British ...
