Calcium carbonate, CaCO3, is the major component of seashells and is effected by an environment where more carbon dioxide is dissolved in water.
H+ (aq) + CaCO3 (s) ↔ Ca+2 (aq) + HCO3‒2 (aq)
- What is happening to the solid calcium carbonate in the reaction above? What does that mean to the structure of seashells?

Thinking about considerations of acid/base chemistry and solubility constants. Calcium carbonate (CaCO3) is added to initially pure water that is exposed to the atmosphere with 400 ppm(v) of carbon dioxide. If solid CaCO3 remains after a long time – showing dissolution and precipitation are at equilibrium – what is the aqueous concentration of calcium ions? Use the acid constants, Henry’s Law constants and solubility products.
