One of the chemical products Phosphoric acid is a colorless, odorless, crystalline solid or a thick syrupy liquid. Physical state is strength and temperature-dependent.
Concentrated phosphoric acid occurs as a colorless, odorless, syrupy liquid. It has a pleasing acid taste when suitably diluted.
Pure phosphoric acid, also called orthophosphoric acid, is a clear, colorless, mineral acid with moderate strength. It is normally marketed as an aqueous solution of 75–85% in which it exists as a clear, viscous liquid
One of the chemical products Phosphoric acid appears as a clear colorless liquid or transparent crystalline solid. The pure solid melts at 42.35°C and has a density of 1.834 g / cm3. The liquid is usually an 85% aqueous solution. Shipped as both a solid and liquid. Corrosive to metals and tissue. Used in making fertilizers and detergents and in food processing.|DryPowder; Liquid; OtherSolid|Clear, colorless, viscous liquid|Solid|HYGROSCOPIC COLOURLESS CRYSTALS.|Thick, colorless, odorless, crystalline solid.|Thick, colorless, odorless, crystalline solid.

Used in making fertilizers and detergents and in food processing.|Phosphoric acid is a phosphorus oxoacid that consists of one oxo and three hydroxy groups joined covalently to a central phosphorus atom. It has a role as a solvent, a human metabolite, an algal metabolite, and a fertilizer. It is a conjugate acid of a dihydrogen phosphate and a phosphate ion.|Phosphoric Acid is a colorless, odorless phosphorus-containing inorganic acid. Phosphoric acid is a sequestering agent that binds many divalent cations, including Fe++, Cu++, Ca++, and Mg++.|Phosphoric Acid is a colorless, odorless phosphorus-containing inorganic acid. Phosphoric acid is a sequestering agent that binds many divalent cations, including Fe++, Cu++, Ca++, and Mg++. Phosphoric acid is used in dentistry and orthodontics as an etching solution, to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed. In addition, phosphoric acid is a constituent in bone and teeth and plays a role in many metabolic processes.
