Industrial & Fertilizer-Grade Chemical
Phosphoric Acid is a versatile mineral acid supplied by ARASCO Conster Action Limited to customers in fertilizer production, metal surface treatment, water treatment, and chemical manufacturing industries.
Phosphoric Acid (chemical formula H₃PO₄, CAS No. 7664-38-2), also known as orthophosphoric acid, is a colorless, viscous, non-volatile mineral acid, freely soluble in water and alcohol. It is typically produced via the wet-process method — reacting phosphate rock with sulphuric acid — then purified and concentrated to the standard commercial range of 75–85% H₃PO₄.
