Phosphoric acid (also known as orthophosphoric acid) is a mineral (inorganic) acid; it has the chemical formula H3PO4.

In addition to being a chemical reagent, phosphoric acid has a wide variety of uses; it is often used as a rust inhibitor, food additive, electrolyte, dispersing agent, industrial etching agent, fertiliser feedstock, and as a component of home cleaning products.

Phosphoric acid 75% is colourless, odourless, non-volatile, viscous but still pourable. Because it is a concentrated acid, an 75% solution can be corrosive, although increasingly non-toxic as it is diluted.

Food-grade phosphoric acid (E number E338) is used to acidify foods and beverages such as cola drinks; it provides a tangy or sour taste, and being a mass-produced chemical is available cheaply and in large quantities.

Phosphoric acid may be used as a ‘rust converter’, by direct application to rusted iron, steel tools, or surfaces. The phosphoric acid converts iron oxide, Fe2O3 (rust), to black ferric phosphate, FePO4.

Among other applications, phosphoric acid is also used:

As a cleaning solution in the construction industry to remove mineral deposits, cement smears, and hard water stains.

As a chelating agent in some household cleaners aimed at similar cleaning tasks.

In hydroponics as a pH reducing preparation to lower the pH of nutrient solutions. While other types of acids can be used, phosphorus is a nutrient used by plants, especially during flowering, making phosphoric acid particularly useful for this application.

As a pH adjuster in cosmetics and skin-care products.

As a dispersing agent in detergents and leather treatment.

As an additive to stabilise acidic aqueous solutions within a specified pH range.
