The formation of limestone (calcification) follows the chemical reaction Ca<sup>++</sup> + 2HCO<sub>3</sub><sup>-</sup> ⇔ CaCO<sub>3</sub> + H<sub>2</sub>O + CO<sub>2</sub> | The formation of limestone (calcification) follows the chemical reaction Ca<sup>++</sup> + 2HCO<sub>3</sub><sup>-</sup> ⇔ CaCO<sub>3</sub> + H<sub>2</sub>O + CO<sub>2</sub> | ||
