[0002] With the development of the country and science and technology, the market share of phosphorous acid is gradually increasing. Phosphorous acid is an inorganic compound with the chemical formula H3PO3. It appears as a white crystalline powder and is easily soluble in water and ethanol. It can be oxidized into orthophosphoric acid in the air and hydrolyzed into phosphite in water. It has the characteristics of high acidity, strong hygroscopicity, strong reducing ability, and good metal ion complexing performance. It is a chemical that can be widely used in industry and agriculture.
