copper oxide and sulfuric acid

copper oxide and sulfuric acid

How does copper oxide and sulphuric acid react to eachother?

Mixing copper oxide and sulphuric acid is an experiment involving an insoluble metal oxide which is reacted with a dilute acid to form a soluble salt. Copper (II) oxide, is a black solid, which, when reacted with sulphuric acid creates a cyan-blue coloured chemical called copper II sulfate.

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. Fromthis solution, blue copper(II) sulfate pentahydrate crystals may be obtained if desired.

Copper Mining and Extraction: Oxide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. A by-product of the smelting and converting furnaces is sulfuric acid.
