QAIPMT-2010-Ch-1940: NEET 2010 Chemistry - Class 11 AIPMT-2010-Ch-1940 Solution: Some statements about heavy water are given below: (i) Heavy…
Some statements about heavy water are given below: (i) Heavy water is used as a moderator in nuclear reactors. (ii) Heavy water is more associated than ordinary water. (iii) Heavy water is more effective solvent than ordinary water. Which of the above statements are correct?
Multiple Choice Options
- A (i) and (ii)
- B (i), (ii) and (iii)
- C (ii) and (iii)
- D (i) and (iii)
Step-by-Step Verified Solution
Heavy water is used for slowing down the
speed of neutrons in nuclear reactors, hence used
as moderator. Boiling point of heavy water is greater
(374.42 K) than that of ordinary water (373 K), hence
heavy water is more associated. Dielectric constant
of ordinary water is greater than that of heavy water,
hence ordinary water is a better solvent.
