Chemical Properties
Easily soluble in water, aluminum sulfate in pure sulfuric acid insoluble (only co-exist), in sulfuric acid and sulfuric acid together dissolved in water solubility of aluminum sulfate in sulfuric acid is aluminum sulfate in water solubility.
Precipitation at room temperature with 18 molecules of crystal water, aluminum sulfate to 18, more than 18 industrial production of aluminum sulfate. 51.3% with anhydrous aluminum sulfate, 100 degrees and will not even dissolve (dissolved in its own crystal water).
Easily weathered the loss of crystal water, more stable, heat will be water loss, high temperature will decompose to alumina and sulfur oxides.

Application
‹1› Aluminum sulfate is a widely used industrial reagent, usually mixed with alum. Aluminum sulfate is usually used as flocculants for water purification and sewage treatment facilities were also used for the paper industry.
‹2› Under natural conditions, little to no aluminum sulfate salt form. It will form a hydrate, including 16 water aluminum sulfate is the most common.
‹3› Aluminum sulfate is also a very effective insecticide mollusks can kill the Spanish slug (Spanish slugs).
‹4› Aluminum sulfate for water and in textile dyeing and printing as a medium. In water purification, it makes impurity condensation, sedimentation and filtration easier.
‹5› When dissolved in a large number of neutral or slightly alkaline water, the produced precipitate of aluminum hydroxide, Al (OH) 3. When dyeing fabric, aluminum hydroxide gel makes it easier to dye attached to the top of plant fiber.
‹6› Aluminum sulfate is also used to adjust soil pH, because it is also hydrolysis of aluminum hydroxide produced a small amount of dilute solution of sulfuric acid.

Storage Precautions
Store in a cool, ventilated warehouse. Away from fire and heat. Oxidant should be kept separate, should not have mixed storage. Storage areas should be equipped with suitable host material spill.

Waste Disposal Method
Disposal should be read before the national and local relevant laws and regulations. During and after the use of safe landfill disposal method.

Transportation Note
To complete the time of shipment packing, loading should be conservative. Transportation process to ensure that the container does not leak, did not fall, not fall, no damage. Strictly prohibited and oxidant, food chemicals, etc. mixed mixed transportation. Transportation should prevent exposure, rain, anti-high temperature. Transport vehicles should be completely finished cleaning.
