Phosphoric Acid

KASEL Chemicals

Synonims: orthophosphoric acid, phosphoric (V) acid 

Phosphoric acid is an inorganic mineral acid having the chemical formula H3PO4. Alternatively, orthophosphoric acid molecules can combine with themselves to form a variety of compounds referred to as phosphoric acids in a more general way. The term "phosphoric acid" can also refer to a chemical or reagent consisting of phosphoric acids, usually mostly orthophosphoric acid. Phosphoric acid is prepared by adding sulphuric acid to calcium phosphate rock. In its anhydrous form the acid is a white solid. While phosphoric acid has the potential to release three hydrogen ions, in aqueous solution only two are available due to the fact that PO4-3 is a stronger base than hydroxide.

Chemical formula: H3PO4 Rel. mol. weight: 98.0 CAS No.: 7664-38-2 EINECS No.: 231-633-2 UN No.: 1805

Density (20°C): 1.71 g/cm³ Solubility in water (20 °C): soluble Melting point: ~21 °C Boiling point: 158 °C

Applications:
Phosphoric Acid is used as clining agent , enhancer acidulant, nutrient of yeast, produce food grade phosphates.

Storage terms
Phosphoric Acid must be stored to avoid contact with metals  and strong caustics, because violent reactions occur. Keep containers tightly closed in a cool, well-ventilated place. Store in well-insulated area. Store protected from moisture & heat. Keep at temperature above 16 °C. Provide a catch-tank & an impermeable corrosion resistant floor with drainage to a neutralization tank within a bunked area.
