Aluminum sulfate is widely used in industry. It can be used as a sizing agent in papermaking, as a flocculant and sewage purifier in water treatment, and many other uses, which are related to its own chemical properties. It is related. Its chemical properties make it widely used in many fields. The following editor will introduce its chemical properties.
1. It is not easy to be weathered and lose crystal water. It is relatively stable. Heating will lose water. After high temperature treatment, it will be decomposed into oxides of alumina and sulfur.
2. When heated to 770℃, it 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 boils 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. It is easy to 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 above editor introduced the chemical properties of aluminum sulfate. It can chemically react with a variety of substances, and can also produce new products after high temperature treatment. Therefore, in its application, it can be used flexibly. There are many uses, and the product after its reaction treatment can also be widely used.
