Definition and Areas of Use :
Sodium acid pyrophosphate is a chemical derivative of phosphorus, which is an important element for life in all living things. It is one of the most common elements found in nature and is naturally formed in foods, water and our bodies. In our bodies, phosphorus participates in the structure of genes, teeth, bones and even muscles. Another important phosphorus derivative that we all use in our daily lives is phosphoric acid. Orthophosphate salts are formed from phosphoric acid, which is a tribasic acid, by changing the position of one, two or all three hydrogen ions with other positive ions.
Phosphoric acid is combined with other elements such as calcium, potassium and sodium and turns into phosphates with heat. The main characteristics that determine the important qualities of phosphates are; chain length and pH. These affect the usability of phosphates, promote solubility with buffering power, chelating power, dispersion and absorptive capabilities. Phosphates are mostly used by forming compounds with phosphate ions of some common elements such as sodium, calcium, potassium and aluminum. Phosphates are divided into groups according to the number of phosphorus atoms they have; They have the following general names.
