Calcium chloride is solid at room temperature, but it also exists as a solution. This substance has a high solubility in water and is often covered with water and is usually associated with 2 water molecules. This compound strongly absorbs moisture and is known as a moisture absorber. The interesting feature of this molecule is the release of heat while dissolving in water, which is due to the high solubility enthalpy of this substance.

Calcium chloride can be produced from the reaction between calcium carbonate (limestone) and hydrochloric acid. In the United States, calcium chloride is produced by purifying natural salt water obtained from salt lakes and salt deposits.
