抄録

The chemical reactivity of Zn is usually attributed to the presence of impurity elements. The present paper however shows that the “Localization Theory” does not hold in our case. The chemical reactivity as determined by measuring the rate of H2 evolution in HCl is more than ten times as high in E-Zn as that in commercial products of “high grades” which are indeed much less pure. In the laboratory products whose trace impurities are almost the same in quality and quantity, the reactivity of E-Zn varies with electrolysing conditions, but always exceeds that of D-Zn by the factor of about ten.
