Phosphoric acidCAS:7664-38-2 is also known as orthophosphoric acid (with the molecular structure formula H3PO4). The pure form is a colorless transparent viscous liquid or rhombohedral crystal, odorless and very sour in taste. 85% phosphoric acid is a colorless transparent or slightly tinted, viscous liquid. Its melting point is 42.35℃, its specific gravity is 1.70, and it is a high-boiling acid that can be dissolved in water in any ratio. At 213℃ (losing half of the water), it forms pyrophosphate. When heated to 300℃, it turns into metapropionic acid. The relative density is 181.834. It is easily soluble in water and ethanol. Phosphoric acid is a common inorganic acid and is a moderately strong acid. Its acidity is weaker than sulfuric acid, hydrochloric acid and nitric acid, but stronger than acetic acid, boric acid and carbonic acid.
