2022-05-19

Calcium chloride is composed of chlorine and calcium, with the chemical formula of CaCl2. Calcium chloride is a colorless cubic crystal. It is a white or gray white powdery solid at room temperature. It has strong hygroscopicity and is soluble in water. What we can know is that calcium chloride can be used as desiccant in industrial production and gas drying. What is the principle that calcium chloride can be used as desiccant?

Calcium chloride is generally a solid of porous blocks, and desiccant is a kind of water remover that absorbs moisture from the atmosphere. Its drying principle is to absorb water molecules in the air through chemical means, and change its chemical structure through chemical reaction. In this way, it will become another substance, so as to achieve the purpose of drying.

To sum up, we can know that because calcium chloride is hygroscopic, calcium chloride can absorb water molecules in the air through chemical reaction and become crystalline calcium chloride, which can achieve the purpose of drying.
