A bottle of dry ammonia and a bottle of ...

A bottle of dry ammonia and a bottle of dry hydrogen chloride connected through a long tube are opened simultaneously at both ends. The white ammonium chloride ring first formed will be

A

a white ring is formed at the centre of the tube

B

a white ring is formed near the ammonia bottle

C

entire length of tube turns white

D

a white ring is formed near HCl bottle

Text Solution

Verified by Experts

The correct Answer is:
D
`"Rate of diffusion " prop (1)/(sqrtM)`
`"Rate of diffusion of "NH_(3)` is greater than `HCl`
Hence white ring of `NH_(4)Cl` will be formed near `HCl`.
