Hot Mono- And Di-potassium Salts Of Fungicide Phosphorous Acid With Wholesale Price
Basic Information
Colorless crystals. The relative density is 1.651 (21.2°C). Melting point 73,6 ℃. The boiling point of 200 ° C (decomposition). Soluble in water and alcohol. It is slowly oxidized into orthophosphoric acid in the air, and decomposed into orthophosphoric acid and phosphine (highly toxic) when heated to 180 °C. Phosphorous acid is a dibasic acid, and its acidity is slightly stronger than that of phosphoric acid. It has strong reducibility and can easily reduce Ag ions to metallic silver, and can reduce sulfuric acid to sulfur dioxide. It has strong hygroscopicity and deliquescence, and is corrosive.
