What Is the Connection between Copper and Sulfuric Acid?

11/1/2021Producing electricity from copper sulfate is done using a solution of diluted sulfuric acid and anhydrous copper sulfate. Using diluted sulfuric acid will not oxidize the copper metal to be used as an electric plate. By using a copper plate, a zinc plate, and electric wires, it is possible to send the extra charge from the ions the salt makes in the weak acid to a small light
