Phosphorus: Chemical Reactions of Phosphorus and Its Importance Abstract: Aluminum sulfate reacts with phosphates to create aluminum phosphate and a sulfate. The conversion of the phosphate to aluminum phosphate is very important because this allows the phosphate to be easily extracted. This manipulation is used today in industrial waste treatment sights. The removal of phosphates is very important for if phosphates are not removed, they plague bodies of water by feeding algae which clog the surface waters and eventually effect every living and nonliving thing in that environment.
