Gardening

The interesting use of aluminum sulfate around the house is in gardening. Because aluminum sulfate is very acidic, sometimes added to the soil that is very alkaline to balance the pH for plants. When aluminum sulfates come into contact with water, it forms aluminum hydroxide and a dilute solution of sulfuric acid, which changes the acidity of the soil. 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

One of the most important uses of aluminum sulfate is in 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.
