Does polyferric sulfate react with alkali?

Does polyferric sulfate react with alkali
 

Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. Its morphological property is light yellow amorphous powder solid, and it is easily soluble in water. So will it react with alkali? It has always been concerned by users. Here is a brief analysis of the following sources:

 

 Polyferric sulfate and alkali reaction
 

Polyferric sulfate is literally a polymer of sulfuric acid and iron (ferrous iron). In other words, sulfuric acid is a kind of strong acid, so it can be concluded that polymerized ferric sulfate is acidic, and the pH value of polymerized ferric sulfate is 2.4, which belongs to acidic substance.
 

Base refers to the substance that all anions ionized in aqueous solution are oh -, that is, hydroxyl ion. There are many alkaline substances. Sodium hydroxide, flake alkali, compound alkali and lime, as we often say, belong to alkali. The pH value of alkaline substance is above 8.
 

Speaking of this, do you not know that polyferric sulfate and alkali do not react? Yes, polyferric sulfate and alkali will react.
 

Acid and alkali together will have a neutralization reaction to produce salt and water Acid base reaction
 

From the above description, we can draw the conclusion that polyferric sulfate reacts with alkali.
