How does sulfuric acid react with copper oxide?

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. read more

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. read more

Copper does not react with dilute sulphuric acid as its reduction potential is higher than that of hydrogen. Copper does not displace hydrogen from non-oxidising acids like HCl or dilute H2SO4. But, concentrated sulphuric acid is an oxidising agent. read more
