 In the field of inorganic chemicals, phosphorous acid (H₃PO₃) is an important compound with unique chemical reactivity and extensive application value. Although its name is similar to phosphoric acid, their properties are significantly different. This dibasic medium-strong acid plays an indispensable role in industrial production and scientific research. In terms of basic properties, phosphorous acid appears as white or light yellow crystalline powder at room temperature, with a special garlic-like odor, a characteristic that makes it easy to identify. It has good solubility, being not only highly soluble in water but also miscible with organic solvents such as ethanol. It oxidizes slowly to phosphoric acid when exposed to air, so it should be stored in a sealed container to prevent moisture absorption. The core of its chemical properties is strong reducibility; it can react with various oxidizing agents such as silver ions, halogens, and hydrogen peroxide. For example, it can red...
