What is Phosphonsure?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Phosphonsure which has developed particularly rapidly in recent years. Do you know about Phosphonsure?
- The official answer: Phosphite is an inorganic compound with the chemical formula H3PO3 and a molecular weight of 82.00.
It is easily soluble in water and alcohol. It is slowly oxidized to phosphoric acid in the air and decomposed to phosphoric acid and phosphine (highly toxic and explosive) when heated to 180℃. Phosphite is a dibasic acid, its acidity is slightly stronger than phosphoric acid, it has strong reducing properties, easily reducing silver ions (Ag+) to metallic silver (Ag), and can reduce sulfuric acid to sulfur dioxide. It has strong hygroscopicity and deliquescence and is corrosive. Phosphite is mainly used as the reducing agent, nylon whitening agent, also used as raw materials for phosphite, pesticide intermediates, and raw materials for organophosphorus water treatment chemicals.
