An electrolyzing apparatus using a circulating capillary tube type mercury bundled electrode is disclosed, in which the advantage of mercury that it has a high overpotential for hydrogen evolution reaction compared with the general solid metals is preserved, and the disadvantage of mercury that it cannot be so shaped as to have a large contact area is overcome. That is, the mercury contact area is maximized. The oxidation and reduction reactions which occur in the vertically circulating capillary tube type mercury bundle electrode electrolyzing apparatus can be defined by a simple formula so as to quantize their analysis. Based on this formula, the stability checking, and the adjustment of the oxidation state of metal ions in the solution can be carried out in a rapid and continuous manner. Further, the concentration of the metal ions and the oxidation state of the metal ions within the solution can be analyzed in the same manner.
