Calcium chloride granules are constituted of the chemical compound calcium chloride (CaCl2), which is made up of the ions calcium and chlorine. It is widely employed in a variety of industries and applications because it is extremely soluble in water. One calcium ion (Ca2+) and two chloride ions (Cl-) make up each calcium chloride molecule, according to the chemical formula CaCl2. Calcium chloride granules are typically colourless or white and have a crystalline appearance. They rapidly collect moisture from their surroundings because they are hygroscopic. This feature of calcium chloride, which is still present in the granular form, is that it is very soluble in water.
