CaCl2 is neutral. It does not ionize to make hydrogen ions, nor dissociate to give ions to hydroxide.
Calcium chloride, CaCl2is a salt. At room temperature, it is white coloured crystalline solid and is extremely water-soluble. It can be formed by neutralizing the hydrochloric acid with calcium hydroxide.
These compounds are used essentially to de-icing and monitor dust. It is used as a desiccant since the anhydrous salt is hygroscopic.
