Phosphoric acid is used for metal cleaning and refining, as well as fertilizer manufacturing. It’s also found in disinfectants and detergents. With those usages, it’s not so surprising that this acid is commonly found on lists of “ strong acids ” or chemicals commonly used in industry that can cause chemical burns.
8) Phosphoric acid The principal use of phosphoric acid is as a rust remover, but it is also used in many commercial limescale cleaners and is found in some soft drinks, notably cola. In the film, Limescale, the main character stops drinking water and only drinks cola in the belief that limescale is building up in his body and cola will dissolve the hardened deposits.
H3PO4, H2PO4 (phosphoric acid and dihydrogen phosphate) Ka = 7.24 x 10-3 b. CH3COOH, CH3COO- (acetic acid and acetate ion) Ka = 1.75 x 10-5 C. H2CO3, HCO3- (carbonic acid and bicarbonate ion) Ka = 5.1 x 10-7 d. NH4+, NH3 (ammonium ion and
Phosphoric acid will dissolve iron oxide without attacking the other components of the steel (chromium and chromium oxide, nickel, and iron). Acetic Acid The reaction with acetic acid is often slower than phosphoric acid and can be a better choice when the underlying corrosion/staining affects a larger percentage of the substrate.
