Is calcium carbonate soluble in water? | AnswersDrive

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.

Difference Between Sodium Carbonate & Calcium Carbonate .

Calcium carbonate occurs naturally in a number of raw forms, including marble, chalk, limestone and the shells of sea creatures. The primary raw sources of sodium carbonate are trona ore or the mineral nahcolite, a raw form of sodium bicarbonate. Processors heat these materials to derive sodium carbonate.

Calcium carbonate - Infogalactic: the planetary knowledge core

Calcium carbonate will react with water that is saturated with carbon dioxide to form the soluble calcium bicarbonate. CaCO 3 + CO 2 + H 2 O → Ca(HCO 3) 2. This reaction is important in the erosion of carbonate rock, forming caverns, and leads to hard water in many regions.

In the case of calcium carbonate, the enthalpy of hydration is not large enough to overcome the large lattice energy, hence it exists as a solid. Do note that solubility of ionic compounds are not absolute. In fact, solubility in water is often given as a value in g/L of water. However, generally, we define solubility as:
