Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl2. It is a white crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide.
Calcium chloride anhydrous has the chemical formula CaCl2, which means it contains one calcium ion bonded to two chloride ions. On the other hand, calcium chloride dihydrate has the chemical formula CaCl2·2H2O, indicating that it contains one calcium ion bonded to two chloride ions and two water molecules.
13 Ιαν 2015 · To provide an idea of how much solid calcium chloride to add, about 120 grams of ‘near-anhydrous’ solid per liter of water produces about a 10 percent solution (roughly 1 lb/gal in US units). If the dihydrate form is used, the amount of the solid would need to be about 1/3 greater than for anhydrous.
It can exist as a white powder in its anhydrous form or as white to colorless crystals when hydrated. In terms of its chemical properties, calcium chloride is highly soluble in water and releases a significant amount of heat upon dissolution.
6 Απρ 2024 · This material is then dried and flaked to produce commercial calcium chloride dihydrate (77 – 82% CaCl 2) and anhydrous (94 – 97% CaCl 2) products. Alternatively, anhydrous pellets can be manufactured through substitution of the flaker with an agglomeration procedure.
Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl2·nH2O, where n = 0, 1, 2, 4, and 6. These compounds are mainly used for de-icing and dust control. Because the anhydrous salt is hygroscopic and deliquescent, it is used as a desiccant.
