(i) It is an ionic compound.
(ii) It is a crystalline solid which is white in colour at room temperature.
(iii) It is highly soluble in water and hence hygroscopic in nature.
(iv) It is odorless.
(v) Its molecular formula is ${CaCl}_{2}$ .
Because of hygroscopic in nature, anhydrous calcium chloride is used to remove water vapor.
