Aluminum sulfate powder is water-soluble. Its main application is drinking water purification and wastewater treatment, as a coagulating agent (assisting the collision of particles by neutralizing the load), and in the production of paper.
It is a common vaccine adjuvant that works to facilitate the slow release of the antigen from the vaccine store formed at the site of inoculation.
Used in the food industry as a firming agent, where it takes E number E520, and also in animal feed as a bactericide. Aluminum sulfate can also be used as a deodorant, astringent, or as a remedy for superficial shaving wounds.
When dissolved in a large amount of neutral or slightly alkaline water, aluminum sulfate produces a gelatinous precipitate of aluminum hydroxide, Al (OH) 3. In dyeing and printing fabrics, the gelatinous deposit helps the dye adhere to the fibers of the garment, rendering the pigment insoluble.
Aluminum sulfate is sometimes used to lower the pH of garden soil as it hydrolyzes to form an aluminum hydroxide precipitate and a dilute sulfuric acid solution. An example of what changing soil pH levels can do to plants is seen when we look at Hydrangea macrophylla. The gardener can add aluminum sulphate to the soil to lower the pH, which in turn will cause the hydrangea flowers to change color (blue). It is aluminum that makes the flowers blue; at higher pH, aluminum is not available to the plant.
In construction it is used as a waterproofing agent and accelerator in concrete. Another application is a foaming agent in a fire foam.
