barium and strontium i.e., CaCl₂.6H₂O, BaCl₂.
2H₂O, SrCl₂ . 2H₂O, can be achieved by heating.
These become wet on keeping in air. Which of
the following statements is correct about these
halides?
(a) act as dehydrating agent
(b) can absorb moisture from air
(c) tendency to form hydrate decreases from
calcium to barium

Answer 2

(d) All of the above

Explanation:

Halides of calcium, barium and strontium act as dehydrating agent as they are hygroscopic in nature. They absorb moisture from air. They also have a tendency to form hydrate which decreases from Calcium to Barium, due to increase in size and decrease in polarization power.

Option D is the answer.
