Phosphoric Acid Manual - DocShare.tips

Phosphoric acid is a triprotic acid which means that, in an aqueous solution, it will dissociate to produce three hydrogen ions. Phosphoric acid is a stronger acid than the organic acids, such as acetic, citric and lactic; however it is not as strong as other mineral acids, such as nitric, sulfuric and hydrochloric.
