Turbid Water Purifier White Powder Aluminum Sulfate

Product Description Chemical Properties of Aluminum Sulfate Not easy to weather and lose water of crystallization, relatively stable, heating will lose water, high temperature will decompose into aluminum oxide and sulfur oxide. Heating to 770 ° C begins to decompose into aluminum oxide, sulfur trioxide, sulfur dioxide and water vapor. Soluble in water, acid and alkali, insoluble in ethanol. Aqueous solution is acidic. Hydrolyzed to produce aluminum hydroxide. Aqueous solution boiling for a long time can generate alkaline aluminum sulfate. Non-toxic, dust can irritate eyes. Hydrolysis products have colloidal precipitates of alkali salts and aluminum hydroxide. Easily combined with potassium, sodium and ammonium salts to form alum, such as potassium aluminum sulfate. On heating the hydrate, it swells violently and becomes spongy, and on heating to a red heat, decomposes into sulfur trioxide and aluminum oxide.
