Reacting copper(II) oxide with sulfuric acid
Class practical
In this experiment an insoluble metal oxide is reacted with a dilute acid to form a soluble salt. Copper(II) oxide, a black solid, and colourless dilute sulfuric acid react to produce copper(II) sulfate, giving a characteristic blue colour to the solution. From this solution, blue copper(II) sulfate pentahydrate crystals may be obtained if desired.
Lesson organisation
This is a well-tried standard class experiment. It should take no more than 30 minutes to produce the filtered salt solution.
Experimental work can begin without delay if the dilute sulfuric acid and copper(II) oxide powder are provided in ready–measured quantities. See Technical notes.
The procedure below could be used by students. A demonstration aided by students may be more sensible if there are real doubts about safe behaviour or adequate manipulative skills.
