1.	Dehydration of hydrates of halides of calcium, barium and strontium i.e., CaCl_(2)6H_(2)O, BaCl_(2)2H_(2), SrCl_(2)*2H_(2)Ocan be achieved by heating. These become wet on keeping in air. Which of the following statements is correct about these halides?
Answer» Act as dehydrating agent Can absorb moisture from air Tendency to FORM HYDRATE decreases from CALCIUM to barium All of the above Solution :CHLORIDES of alkaline earth metals are hydrated. These are hygroscopic in nature.
