2021-10-20 · However, if carbon dioxide is passed in excess, it forms the soluble calcium hydrogen-carbonate. Ca(OH) 2 + CO 2 → CaCO 3 + H 2 O. Properties of CaCO 3. It is a fluffy powder. It decomposes to give carbon dioxide when heated up to 1200K. When it reacts with dilute acid, it liberates carbon dioxide as a by-product.
Loevenhart and Crandall 1 have recently suggested the use of calcium carbonate in the treatment of the gastric hyperacidity syndrome. The reason for suggesting it was that calcium carbonate is a very insoluble substance and that the suspension is apparently neutral in reaction, although it has a high neutralizing power for acids.
Calcium carbonate has a very low solubility in pure water (15 mg/L at 25°C), but in rainwater saturated with carbon dioxide, its solubility increases due to the formation of more soluble calcium bicarbonate. Calcium carbonate is unusual in that its solubility increases as the temperature of the water decreases.
