Phosphoric Acid 85% Chemical appearance:

Phosphoric Acid 85%  is an aqueous solution that is colourless, odourless and not volatile. It presents in the form of a syrup, thick but still pourable. The basic conjugate base of this acid is a dihydrogen phosphate anion which is a mix of hydrogen and phosphate ions.

Chemical application and strengths:

• • Manufacturers produce two main grades of phosphoric acid: food grade and industrial grade. Food manufacturers add food-grade phosphoric acid to foods and beverages to provide a mildly acidic or tangy taste. Beverage manufacturers commonly use it in colas, while food producers use it in products such as jams.
  • Food manufacturers also use phosphoric acid as a nutrient source in yeast-containing foods. It supports yeast growth during production while helping limit the growth of unwanted microorganisms. In sugar production, manufacturers use phosphoric acid as a reaction catalyst.
  • Industrial manufacturers use phosphoric acid as a drying agent, catalyst, and cleaning agent. Chemical manufacturers also use it to produce various chemical treatment solutions, phosphates, and electrolyte treatment solutions.
  • In the metal-processing industry, manufacturers apply phosphoric acid as a protective coating to help prevent rust and corrosion on metal surfaces.
  • Semiconductor manufacturers use phosphoric acid in the production and processing of liquid-crystal display films and electronic chips and use it to clean these products.
  • Although phosphoric acid is generally classified as a weak acid, it exhibits the characteristic properties of an acid. It also acts as a sequestering agent, binding with divalent metal cations such as iron and magnesium. Manufacturers and formulators use this property in various electrolyte-correction applications across the food and industrial sectors.
