copper ii oxide and excess sulphuric acid

copper ii oxide and excess sulphuric acid Prominer ...

when sulfuric acid and copper (II) oxide are allowed to react . Add excess copper (II) oxide or copper (II) hydroxide or copper (II) carbonate (NOT copper metal!!!!!) to dilute sulphuric acid. Copper cannot be used because copper does not react with acid. It is less reactive than hydrogen gas and is unable to displace hydrogen from sulphuric acid.
