Phosphoric Acid

Phosphoric acid, also known as orthophosphoric acid, pure product is colorless transparent viscous liquid or rhombohedral crystals, odorless, taste very acidic. 85% phosphoric acid is colorless transparent or slightly light-colored, thick liquid. Melting point 42.35 ° C, specific gravity 1.70, high boiling point acid, can be mutually soluble with water at any ratio, boiling point 213 ° C (loss of 1/2 water), then generated pyrophosphoric acid. When heated to 300℃, it becomes metaphosphoric acid. Relative density 181.834, soluble in water, soluble in ethanol.

Mainly used in phosphate industry, electroplating, polishing industry, sugar industry, composite fertilizer and so on. In the food industry as acidifier, yeast nutrient, etc.
