Calcium chloride, an inorganic compound of calcium and chlorine, exists primarily in two forms: calcium chloride anhydrous (CaCl2 0H2O) and calcium chloride dihydrate (CaCl2 2H2O). The anhydrous form is a white, hygroscopic solid, while the dihydrate appears as white crystalline granules or powder. With a density of approximately 2.15 g/cm³, calcium chloride is notable for its high solubility in water, a characteristic that intensifies with increasing temperature. This aspect, known as calcium chloride in water, plays a crucial role in its applications. Additionally, the calcium chloride pH is a significant factor in its diverse applications across food processing, pharmaceuticals, industrial usage, and oil drilling.
