Generally the degree of electrolytic dissociation of an aqua (protic solvent) is larger than that of a nonaqueous solvent (aprotic solvent). And the electric conductivity of an inorganic salt dissolved in a nonaqueous solvent is smaller than in an aq

Hydroxide solution of alkaline-earth metal is easy to form carbonate by absorbing carbon dioxide in air. This absorption was able to be prevented simply by setting carbon fluoride membrane on the liquid surface. In the present investigation, anodizat
