Product Overview: Phosphoric Acid (H₃PO₄)
Phosphoric acid is a colorless, transparent, and syrupy liquid widely used across numerous industries. It has a melting point of 42.35°C and a relative density of 1.834 g/cm³. When heated to around 300°C, it transforms into meta-phosphoric acid. Known for its acidity and water solubility, phosphoric acid serves as a critical component in fertilizers, food processing, cleaning agents, and rust inhibitors.
At South Chem Trading, we stock both technical (industrial-grade) and food-grade phosphoric acid, available in bulk and various packaging options.
