High-purity Phosphoric Acid Solution 85%

Phosphoric Acid 85% – High-Purity Inorganic Acid for Diverse Industrial Applications   Specification: 35kg/drum   Phosphoric acid, systematically named orthophosphoric acid or phosphoric(V) acid, is a colorless, viscous, syrupy liquid with a characteristic acidic taste and odor. Our high-quality product contains 85.00% H₃PO₄ by weight, representing the standard commercial concentration that balances active acid content with favorable handling properties for food processing, fertilizer manufacturing, water treatment, and diverse industrial applications.   As the most important oxygen acid of phosphorus, phosphoric acid possesses unique chemical characteristics that distinguish it from mineral acids. The triprotic nature of phosphoric acid enables stepwise dissociation (pKa1 2.16, pKa2 7.21, pKa3 12.32), providing versatile pH buffering capacity across a broad range. This property, combined with low volatility, excellent thermal stability, and favorable safety profile, establishes phosp…
