    What Is the Connection between Copper and Sulfuric Acid

    Feb 19, 2021 Copper does not dissolve in many acids, but in concentrated sulfuric acid it breaks up by reacting. Combining copper and sulfuric acid can produce hydrates, or copper ions that are stuck to water. Electricity can be generated when copper comes in contact with the proper sulfuric acid solution.
