Phosphoric acid 85%
Product profile
Phosphoric acid, also known as orthophosphoric acid, is an inorganic acid commonly used in various industries. It has moderately strong acidity, its chemical formula is H3PO4, and its molecular weight is 97.995. Unlike some volatile acids, phosphoric acid is stable and does not break down easily, making it a reliable choice for a variety of applications. While phosphoric acid is not as strong as hydrochloric, sulfuric, or nitric acids, it is stronger than acetic and boric acids. Furthermore, this acid has the general properties of an acid and acts as a weak tribasic acid. It is worth noting that phosphoric acid is hygroscopic and readily absorbs moisture from the air. In addition, it has the potential to convert to pyrophosphoric acid when heated, and subsequent loss of water can convert it to metaphosphoric acid.
