Dissolution and Insolubility

APCHEM-4U18GO

Considering that calcium carbonate is insoluble in water, how can it be used as a dietary supplement?

A

The energy produced from cellular respiration allows it to dissolve better.

B

Stomach acid reacts with the calcium carbonate, leading to calcium ions in solution and the production of water and carbon dioxide.

C

The sodium-potassium pump absorbs the smaller calcium ions while ejecting the carbonate ions.

D

The grinding of the calcium carbonate in the mouth causes a larger surface area, leading to a higher reaction rate and increased solubility.
