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
Pure phosphoric acid is colorless, odorless and has sour odor.
Phosphoric acid is Soluble in water and ethanol. Easily absorb moisture. Easy to be crystallized under cold condition for long time.
Phosphoric Acid is Corrosive. Should be stored in closed containers.
