It is less common in food additives compared to DCP. 6. Production Process: Dicalcium Phosphate (DCP): DCP is typically produced by reacting calcium carbonate (CaCO₃) or calcium hydroxide (Ca(OH)₂) with phosphoric acid (H₃PO₄) in a controlled process. It may also be derived from bone phosphate during the production of bone meal.

Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen …
