Application：

Aluminum sulfate has many different uses in day-to-day life, as well as being used in several essential industries. In fact, you probably come into contact with it on a daily basis without even knowing it!

Household Uses

found in baking soda. Some antiperspirants contain aluminum sulfate because of its antibacterial properties; Finally, the compound is the astringent ingredient in styptic pencils, which are designed to stop small cuts from bleeding.

Gardening

Because aluminum sulfate is extremely acidic, it’s sometimes added to very alkaline soils to balance the pH for plants.  Gardeners who plant hydrangeas apply this property to change the flower color (blue or pink) of the hydrangeas since this plant is very sensitive to soil pH.

Water Treatment

water treatment and purification. When added to water, it causes microscopic impurities to clump together into larger and larger particles. These clumps of impurities will then settle to the bottom of the container or at least get large enough to filter them out of the water. This makes the water safer to drink. On the same principle, aluminum sulfate is also sometimes used in swimming pools to decrease the cloudiness of the water.

Dyeing Fabrics

dyeing and printing on cloth. When dissolved in a large amount of water that has a neutral or slightly alkaline pH, the compound produces a gooey substance, aluminum hydroxide. The gooey substance helps dyes stick to the cloth fibers by making the dye water insoluble. The role of aluminum sulfate, then, is as a dye “fixer,” which means that it combines with the molecular structure of the dye and the fabric so the dye doesn’t run out when the fabric gets wet.

Paper Making

making paper. The aluminum sulfate helped to size of the paper. In this process, aluminum sulfate was combined with rosin soap to change the absorbency of the paper. This changes the ink-absorbing properties of the paper.
