Question

1. A gas jar containing air is placed upside down on a
gas jar of bromine vapour.
It is observed that after some time, the gas jar
containing air also becomes
reddish brown. a)Explain why this happens. b)Name
the process involved.​

Answer 1

Answer:

b) Diffusion

Explanation:

Bromine is a highly volatile element that easily turns into vapour....in its gaseous state ,it is brown in colour and is highly diffusible....so due to diffusion it fills the whole container and colours it brown

Answer 2

Answer:

We observe that, after some time, the red brown vapours of bromine spread out into the upper gas jar containing air. In this way the upper gas jar which contains air in it also turns red-brown.

2. This mixing is due to Diffusion of Bromine vapour into air.
