Phosphoric acid is classified as weak acid as Phosphoric acid undergoes partial dissociation in water solution as it does not fully dissociate into H+ (H3O+) and the dihydrogen phosphate ion when dissolved in water and producing a low concentration of hydrogen ions . So, Phosphoric acid is a weak acid .
Phosphoric acid chemical formula is H ₃PO ₄. Orthophosphoric acid refers to phosphoric acid
In aqueous solutions, phosphoric acid behaves as a triprotic acid. The triprotic acid has three ionizable hydrogen atoms, which are lost sequentially.
