The chemical properties of aluminum sulfate

The chemical properties of aluminum sulfate

Aluminum sulfate is widely used in industry. It can be used as a sizing agent in papermaking, as well as a flocculant and sewage purifier in water treatment. It has many other uses. This is related to its own chemical properties. It is related. Its chemical properties enable it to be widely used in many fields. The following editor will introduce its chemical properties.
　　 1. It is not easy to weather and lose crystal water. It is relatively stable. It will lose water when heated. After high temperature treatment, it will decompose into oxides of alumina and sulfur.
　　2. Heating to 770°C begins to decompose into alumina, sulfur trioxide, sulfur dioxide and water vapor.
　　 3. The aqueous solution is acidic. After hydrolysis, aluminum hydroxide is formed. The aqueous solution can boil for a certain period of time to generate basic aluminum sulfate. Non-toxic, dust is irritating to eyes.
　　4. The hydrolyzed product has colloidal precipitation of basic salt and aluminum hydroxide. Easily combine with potassium, sodium, and ammonium salts to form alum.
　　 5. When the hydrate is heated, it expands violently and becomes a sponge. When heated to red heat, it decomposes into sulfur trioxide and alumina.
The editor above is about the chemical properties of aluminum sulfate. It can chemically react with a variety of substances. It can also produce new products after high temperature treatment. Therefore, it can be used flexibly in its applications. In addition to itself, it can be used in industry. There are many uses, and the product after its reaction treatment can also be widely used
