Phosphoric acid - Wikipedia Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a weak acid with the chemical formula H 3 P O 4. It is normally encountered as a colorless syrup of 85% concentration in water. The pure compound is a colorless solid. All three hydrogens are acidic to varying degrees and can be lost from the molecule as H + ions .

Uses of Phosphoric Acid - Science Struck Removal of RustUse in Processed FoodMedical UsesOther UsesOne of the most common uses of phosphoric acid is for the removal of rust from metal surfaces. It acts as a rust converter on direct application to rusted iron, steel, and other metal surfaces. It converts reddish-brown iron, that is, ferric oxide, to black-colored ferric phosphate. After this treatment, the black ferric phosphate coating can be easily scrubbed off, revealing the underlying fresh metal surface. For complete rust removal, multiple applications of phosphoric acid may be needed. In some applications, where exterior appearance is secondary, the black phosphate coating formed on applying this acid may be left in place so that it provides further corrosion resistance. The phosphoric acid based rust remover is a greenish liquid that is suitable for dipping, but it is more often formulated as a gel for easy application. See full list on

Orthophosphoric Acid (H3PO4) [Phosphoric Acid] - Structure ... What Is Phosphoric acid?Synthesis of Phosphoric Acid – H3PO4Physical Properties of Phosphoric AcidChemical Properties of Phosphoric AcidUses of Phosphoric AcidHealth HazardFrequently Asked QuestionsPhosphoric Acid is an acid-containing four atoms of oxygen, one atom of phosphorus, and three atoms of hydrogen. It is also known as phosphoric(V) acid or orthophosphoric acid. It is present in teeth and bone and helps in metabolic processes. In its liquid form, it appears as a clear, colorless solution and in its solid form, it appears as transparent, crystalline solid. As a sequestering agent, it helps in the binding of divalent cations. It is widely used in orthodontics and dentistry. Phosphoric acid is important in biogeochemistry and biochemistry. It is tribasic acid. The three regions are the region where pH is equal to pK, the region where pH is equal to 4.7 and the region where pH is equal to 9.8. See full list on
