Product Description

Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric(V) acid) is a colorless, odorless phosphorus-containing solid, and inorganic compound with the chemical formula H3PO4. It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non-volatile syrupy liquid. It is a major industrial chemical, being a component of many fertilizers.

Transparent colorless viscous solution, odorless. General content of 85% ~ 95%. Continue to concentrate to obtain colorless columnar crystals, density (18 deg C) 1.834g/cm3, melting point 42.3 deg C, boiling point 158 deg C, freezing point 21.1 deg C. It was heated to 150 ° C. And changed to pyrophosphoric acid and to metaphosphoric acid at about 215 ° C., with a vapor pressure of 300. Strong deliquescence. Miscible with water and ethanol.

Packaging & Shipping

A concentrated solution of phosphoric acid is irritating to the skin and eyes and can corrode the skin to cause inflammation. Phosphoric acid vapor can cause nasal mucosa atrophy, can cause systemic poisoning. The maximum allowable concentration of phosphoric acid in air is 1 mg/ma. If not, the skin contact with phosphoric acid, should immediately rinse with plenty of water, and wipe red mercury solution or gentian violet solution, poisoning phenomenon should be sent to the hospital immediately. It is not allowed to be stored and mixed with alkaline, toxic and corrosive substances.
