Abstract
In order to know the physicochemical properties of magnetized water, the experimental methods of column assay, crystalization of saltsand gypsom have been explored to elucidate the effects of magnetized water on the solubility speed of salts, crystal pattern from salt squeous solutions, and gypsom crystal pattern, respectively. In the column assay for salt solubility the magnetized water showed the decreased initial solubility speed of NaCl and slightly increased initial solubility spped of KCI, however, the maximum solugilities of NaCl and KCI in the magnetized aster were almost same in the double distilled water, respectively. The column assay also indicated that the magnetized water showed the decreased initial solubility speed of urea (CH$_4$N$_2$O), sodium citrate (HOC(CO$_2$Na)-(CH$_2$CO$_2$Na)$_2$-2H$_2$O) and (NH$_4$)$_2$compared to the double distilled water, while slightly increased solubility speed of glycine (NH$_2$CH$_2$COOH), boric acid (H$_3$BO$_3$), MgSO$_4$. Crystalization of 1% or 5% salt aqueous solutions by rapid evaporation disclosed that the magnetized water produced more condensed and bigger crystal structure than the control water. The pattern of gypsom crystal formation also indicated that the magntized water enhanced the crystal formation in the hydration reaction of gypsom plaster compared to the double distilled water. Taken together, it was presumed that the magnetized water showed the different physicochemical properties in the interaction with various salts, especially showed the contrast results between NaCl and KCI.
