Properties
| Physical State | Colorless transparent or slightly pale, viscous liquid |
|---|---|
| Solubility | Can be mixed with water in an infinite proportion, but at the same time it has a dehydration-hydration equilibrium reaction with water. |
| Acidity | Faintly acid |
| Corrosiveness | Phosphoric acid solutions can be corrosive to certain metals and materials. |
| Toxicity | Phosphoric acid is a non-toxic inorganic substance. In laboratory and industry, a mixture of non-toxic phosphates and weak acids (such as citric acid) is often used as a buffer solution. |
| Bleaching | Bleaching agent in industries such as paper and textiles. Sodium metasilicate helps to whiten and brighten materials. |
| Compatibility | Compatible with a wide range of other chemicals and ingredients commonly used in industrial and household formulations. |
Applications
Phosphoric acid can be used as a sour agent in cans and beverages such as cola. It can be used as a yeast nutrient source and PH regulator to prevent the propagation of miscellaneous bacteria in brewing.
Phosphoric acid can be used to make phosphorus-containing drugs, such as Sodium glycerophosphate.
Within rubber and plastic industry, phosphoric acid is used as an acidic catalyst for thermoplastic Phenol resin; Coagulant for slurry and raw materials for producing inorganic inder.
Phosphoric acid is used to produce Sodium.
