Chemical application and strengths:
- The substance is not reactive with most of the naturally occurring elements. However, it reacts with sodium bicarbonate to form a thick blanket of carbon dioxide. A foam stabilizer is added to the reaction to create a viable carbon dioxide layer that can effectively lock out oxygen from the burning material. This is the most common substance in many fire extinguishers used in Japan and India.
- It is also used as a firming industry in the human food industry, especially for starch. It commonly called E520. The same substance is also used in animal feeds to deal with bacteria that may be lurking around. In addition, it is used a deodorant and a septic for use in small superficial wounds. It has also shown effectiveness in improving immunogenicity vaccine for people who have problems with their immunity.
- The other common usage is water purification. Here, it reacts with metal elements in the water to form insoluble substances. These particles then sediment below the container where they can be removed through sieving. This process is called flocculation or coagulation and is common among water suppliers and bottlers.
- Textile printers use aluminum sulfate as a dye fixer or a mordant. It attached itself to the color and prevent it from running when it is being washed It can also be used to adjust the soil PH. In the soil, it hydroxides aluminum hydroxide with the acid that was in the soil. This results t in the soil becoming more neural.
