We have to explain why calcium carbonate (CaCO3), although water-insoluble, can be used to deliver calcium ions (Ca2+) to the musculoskeletal system.
Calcium carbonate (CaCO3), as a calcium supplement, is taken orally. When taken orally, calcium carbonate enters the stomach that contains hydrochloric acid (HCl).
Calcium carbonate, CaCO3, is often used as a dietary calcium supplement for bone health. Although CaCO3(s) is insoluble in water, it can be taken orally to allow for the delivery of Ca2+(aq) ions to the musculoskeletal system.
Why is this the case? [Hint: Recall the reactions of metal carbonates discussed in Section 4.3 in the textbook.]
