Question

Cobalt Chloride forms pink crystals.When they are heated,water is evolved and they turn blue.
.Explain how we could use Cobalt Chloride as a test for water??

Answer 1

The Cobalt Chloride-Hexahydrate I remember is more purple than pink. It is easily dehydrated into blue crystals. The anhydrate is highly hydroscopic (adsorbs water) returning to purple (pink) color. In the anhydrate form, appropriately sized quantities can be placed into desiccators to adsorb and indicate presence of water vapor in the storage area of the desicator.
