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

at the centre of the tube

B

near the hydrogen chloride bottle

C

near the ammonia bottle

D

throughout the length of the tube.

Text Solution

Verified by Experts

The correct Answer is:
B
`r prop 1//sqrt(M)`. Molecular mass of HCl (36.5) is greater than that of `NH_(3)`(17), hence HCl will diffuse slowly, i.e., the ring will be formed near the HCl bottle.
