Chemical compound that is crystalline, lumpy or flaky is usually white and is very soluble in water. It is a salt that is solid at room temperature, and it behaves as a typical ionic halide. The anhydrous compound is hygroscopic; it rapidly absorbs water and used to dry gases by passing through it. Other uses in refrigeration and food preservative.
