  • Reacting copper(II) oxide with sulfuric acid

    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 can be obtained.
