Answer 2

Hey dear,

● Answer -
Dry anhydrous CaCl2 gets converted to liquid solution.

● Explanation -
Anhydrous calcium chloride is hygroscopic in nature. This property is called deliquescence.

When anhydrous CaCl2 is exposed to atmosphere for 2 days, it gets converted to liquid solution.

* To avoid this CaCl2 is stored in airtight containers.
* CaCl2 is used for drying gases in the lab.


Hope this helps you.
