About products and suppliers

The H3PO3 acid name (phosphoric acid) is well known in the scientific community. Phosphoric acid is a mineral found naturally in the earth's crust. It is also produced as a by-product of other human processes. It is used in several industries, including agriculture, mining, manufacturing, and textile.

What is H3PO3?

Phosphoric acid (H3PO3), also known as orthophosphoric acid, is a transparent crystalline solid or a clear, colorless liquid. Chemically, the structure of H3PO3 is represented by the formula HPO(OH)2. It's also used in the industrial fertilizers preparation of albumin derivatives, and the sugar and textile industries. Phosphorous acid is obtained in a volatile white powder by gradually burning phosphorus. Phosphorous acid is an important compound for humans and plants because it helps form phosphates—a mineral essential for building bones, muscles, teeth, cartilage, skin cells, and nerve tissue, as well as assisting with cellular respiration.

Comparison of H3PO3 and H3PO4

The dissociation of H3PO3 takes three steps in an aqueous solution to release all the H+ ions, and the split ions then reform together to make H3PO4. Because H3PO4 does not completely dissociate in water or its aqueous solution, it is considered a weak acid. Although H3PO4 is stronger than H3PO3, it is weaker than H3PO3 in terms of its oxidant capacity. As H3PO3 has a higher polarity, its O-H bonds will be weaker, making H+ easier to remove. The basicity of H3PO3 is 3. H3PO3 PKA (the acidity) value is 2.14. In addition, the molar mass of h3PO3 is 82 g/mol.

What are the applications of H3PO3?

H3PO3 acid is an important industrial chemical and a versatile tool in many areas of chemistry. It can form weak phosphides with other elements, making it an ideal secondary building block for some organic molecules. Phosphoric acid is used as phosphate salt for fertilizers. It is also used in food packaging as a desiccant, emulsifier, reactor poison gas cleanup agent, and preservative agent.
