Phosphoric Acid 75% 1000L - IBC
Phosphoric Acid 75% 1000L - IBC 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, a 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. Phosphoric Acid 75% 1000L 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; 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.
