Phosphoric acid 85% is a concentrated aqueous solution of orthophosphoric acid (H₃PO₄). It is a clear, colorless, odorless, and syrupy liquid that is widely used in food processing, agriculture, industrial manufacturing, and pharmaceuticals.

🏭⚗️ Production
Phosphoric acid is primarily produced via the wet process, in which phosphate rock is treated with sulfuric acid, yielding phosphoric acid and gypsum as a byproduct. The 85% concentration is obtained by removing excess water through evaporation. It can also be produced by the thermal process, which involves burning elemental phosphorus in air and hydrating the resulting P₄O₁₀.

🔬 Properties
Phosphoric acid 85% is a moderately strong acid with a pH around 1.0. It is miscible with water, non-volatile, and has good thermal and chemical stability. It is corrosive to metals and tissue in its concentrated form and acts as a triprotic acid, capable of donating three hydrogen ions.

🧪 Applications
• Food industry: Used as an acidulant (E338) in soft drinks, jams, and processed foods.
• Agriculture: A precursor for phosphate fertilizers like mono- and diammonium phosphate.
• Pharmaceuticals: Used in dental products, anti-nausea syrups, and as a pH adjuster.
• Industrial uses: Applied in metal treatment (e.g., rust removal), cleaning agents, and in the production of detergents and flame retardants.
