Physical Properties of Magnesium Chloride (MgCl2) Magnesium chloride appears as a white to colourless crystalline solid. It is readily soluble in water and ethanol, and is slightly soluble in acetone and pyridine. Magnesium chloride is strongly deliquescent in nature. That is, it has the tendency...
