Phosphoric Acid (H₃PO₄) is a critical inorganic acid with a wide range of commercial uses, valued for its low toxicity (in food-grade form) and strong chemical reactivity. It is produced primarily via two methods: the wet process (using phosphate rock and sulfuric acid) for industrial/agricultural grades, and the thermal process (for high-purity food/pharmaceutical grades).
Core Uses by Industry
Food & Beverage: Acts as an acidulant in carbonated drinks (e.g., cola) to enhance flavor and extend shelf life; also used as a pH adjuster in jams, dairy products, and processed meats.
Industrial Cleaning: Removes rust and mineral deposits from metal surfaces (e.g., automotive parts, machinery) due to its ability to dissolve iron oxides without damaging base metals.
Agriculture: Serves as a raw material for phosphate fertilizers (such as monoammonium phosphate, MAP) to supply essential phosphorus to crops, boosting root development and yield.
Safety Notes
When handling concentrated phosphoric acid (≥85%), wear chemical-resistant gloves and goggles to avoid skin/eye irritation. Dilute with water (add acid to water, not vice versa) to prevent splashing.
