Abstract
A method for manufacturing a sulfuric acid solution includes supplying a chloride ion-containing sulfuric acid solution as an initial electrolyte in an electrolyzer inside of which is divided into an anode chamber and a cathode chamber by a diaphragm; and subsequently taking out a metal dissolved electrolyte in which a metal constituting the anode is dissolved from the anode chamber while supplying a current to an anode and a cathode disposed in the electrolyzer.
